b. The belief systems originated in India.
Step-by-step explanation:
The belief systems are similar because they originated from India.
These belief systems are deep rooted in Hinduism and Buddhism which all originated from India. In hinduism, the understanding of Brahman is from within the Atman (which means self or soul) while in buddhism, it is about finding Anatman (not soul or not self). Hinduism believes that highest life is attained by a process of removing bodily distractions. While buddhism follows a disciplined life.
