Reform Movements Against Idol Worship

The question asks to identify reform movements that specifically objected to the practice of idol worship.

Brahmo Samaj (B)

Founded by Raja Ram Mohan Roy, the Brahmo Samaj advocated for monotheism and the worship of a formless God. It strongly opposed idolatry and polytheism, promoting rationalism and a reform of Hindu practices.

Arya Samaj (C)

Established by Swami Dayanand Saraswati, the Arya Samaj emphasized a return to the teachings of the Vedas, which they considered infallible. A core tenet of Arya Samaj was its opposition to idol worship, caste rigidity, and superstitious rituals prevalent in Hinduism during that era.

Other Movements

While movements like Prarthana Samaj also focused on monotheism and social reform, Brahmo Samaj and Arya Samaj are distinctly known for their strong objections to idol worship as a central reformist principle.

Conclusion: Based on their founding principles and historical objectives, both Brahmo Samaj and Arya Samaj objected to the worship of idols.
