The correct answer is 1850.

In 1850, the government of British India passed the Act XV, which addressed the issue of inheritance rights for those who converted to Christianity. Prior to this Act, individuals who converted often faced the loss of their ancestral property and inheritance rights within their families and communities. The Act of 1850 aimed to alleviate this issue, granting converts certain rights to their ancestral property, although the specifics and application varied depending on the circumstances and existing customary laws. This law played a significant role in the social and legal landscape of the time, impacting both religious freedom and property rights, and consequently altering the dynamics of conversions within India during the British Raj.

This legislative move was a part of the broader socio-political changes occurring within British India. It reflected the evolving engagement of the colonial government with religious matters and the complexities of balancing religious freedom with existing social structures. While the act represented a step towards religious tolerance, its practical implementation often faced challenges in its application due to ongoing disputes about property rights and customary laws within communities. The legacy of this legislation continues to inform discussions on religious freedom, property ownership, and the interplay between colonial policies and social change in India.
