The question asks to identify the person whose significant efforts helped restore communal harmony during the challenging period of the Partition of India.

Understanding the Turmoil of Partition

The Partition of India in 1947 led to widespread communal violence, displacement, and loss of life. Amidst this chaos, several leaders worked towards peace and unity, but one figure's actions stood out for their direct impact on calming tensions and advocating for communal harmony.

Analysing the Options and Key Figures

Let's consider the individuals mentioned in the options and their roles during this critical time:

• B.N. Rau: Sir Benegal Narsing Rau was a distinguished civil servant and international jurist. He played a key role in drafting the Constitution of India and served as India's representative in various international forums. While crucial for India's legal and diplomatic foundations, his primary focus was not directly on field-level work to restore communal harmony during the partition riots.
• Rajendra Prasad: Dr. Rajendra Prasad was a prominent leader in the Indian National Congress and later became the first President of India. He was involved in political negotiations and the establishment of the new government. While committed to national unity, his role was more administrative and constitutional during the immediate post-partition period, rather than directly engaging in efforts to stop communal violence on the ground.
• Mahatma Gandhi: Mohandas Karamchand Gandhi, known as the Father of the Nation, was a relentless advocate for Hindu-Muslim unity throughout his life. During the violence of Partition, Gandhi undertook several initiatives, including fasts unto death in Calcutta (now Kolkata) and Delhi, specifically aimed at appealing to people's consciences to stop the bloodshed and restore peace. He travelled to riot-affected areas like Noakhali in Bengal and Bihar, risking his life to preach non-violence and harmony. His 'valiant efforts' through non-violent resistance and moral persuasion were highly effective in specific areas, significantly reducing violence and fostering reconciliation.
• Maulana Azad: Maulana Abul Kalam Azad was a senior leader of the Indian National Congress and a strong opponent of the Partition on religious grounds. He became India's first Minister of Education. He tirelessly advocated for Hindu-Muslim unity through his speeches and writings. While his intellectual and political contributions to unity were immense, the description "valiant efforts to restore communal harmony" amidst the *turmoil* often specifically refers to direct interventions on the ground to stop violence, which was a hallmark of Gandhi's actions during this time.

Mahatma Gandhi's Role in Restoring Communal Harmony

Mahatma Gandhi was deeply distressed by the communal violence that accompanied the Partition. He saw it as a betrayal of the principles he had fought for. Instead of participating in the celebrations of independence, he chose to be in areas affected by violence, using his moral authority and the technique of fasting to appeal for peace.

• He was in Calcutta just before Independence Day, where his presence and a fast helped quell violence.
• Later, he moved to Delhi, where he undertook another significant fast to pressure leaders and the public to protect Muslims living in the city and promote communal peace.

These actions were widely seen as crucial interventions that helped restore some degree of sanity and communal harmony in severely affected regions.

Conclusion

Considering the description of "valiant efforts to restore communal harmony" amidst the turmoil of the partition, Mahatma Gandhi's specific actions, such as fasting and visiting riot-hit areas to stop violence and advocate for unity, align most closely with this characterization.

Therefore, the person being discussed is Mahatma Gandhi.
