Final answer:
African religions differ from Hinduism mainly in the absence of a centralized religious authority, with African traditional religions presenting localized practices and deities.
Step-by-step explanation:
African religions are unlike Hinduism in C. Centralized religious authority. While Hinduism has a well-established clergy and a relatively organized structure of religious authority, African traditional religions typically do not have a centralized religious authority. Instead, religious practices and beliefs are often localized and individual communities have their own specific deities and religious leaders. African religions commonly include polytheistic beliefs, a strong emphasis on rituals and ceremonies, and practices of ancestor worship. These elements show significant differences from Hinduism but point out the rich diversity and the deeply spiritual nature that is characteristic of many African traditional religions.
