Final answer:
In the caste system in India, the higher the caste, the stricter the rules. The caste system was closely tied to Hindu beliefs, and marrying outside one's caste was thought to generate bad karma. People could be served by individuals from other castes.
Step-by-step explanation:
In the caste system in India, the higher the caste, the stricter were the rules. This is specifically true about the highest caste, the Brahmins, who had strict guidelines related to purity and rituals. People's positions in the caste system were indeed closely connected with Hindu beliefs, specifically concepts of purity, reincarnation, and karma. It wasn't true that individuals could only be served by people in their own caste. Different castes had different occupations, and lower caste individuals often served higher ones. Also, marrying outside one's caste was frowned upon and believed to create bad karma, not good. So, the only true statement is that people in the higher castes had the strictest rules.
