5. Which of the following was a feature of Sikhism during its early development? A. Rejection of monotheism B. Opposition to caste distinctions C. Adoption of Islamic law D. Support for the Mughal emperor's policies

The correct answer is B. Opposition to caste distinctions.<br /><br />Sikhism, during its early development, rejected caste distinctions and promoted equality among all individuals, regardless of their social or economic status. This was a significant departure from the caste-based social hierarchy prevalent in Indian society at the time. Sikhism emphasized the importance of spiritual equality and the rejection of discrimination based on caste or social class.
