Step-by-step explanation:
The correct answer to the question is c) Hinduism. Hinduism is recognized as the world's oldest major religion still in practice today. It emerged about 4,500 years ago in the Indus River Valley, which is part of modern-day northwest India and Pakistan. This religion is predominantly practiced in India, where approximately 80 percent of the population follows Hindu traditions. Unlike other major religions, Hinduism does not have a single founder; instead, it is a synthesis of various traditions and philosophical schools of thought. The religion boasts a rich tapestry of scriptures such as the Vedas, Upanishads, and epic tales like the Mahabharata and Ramayana. Key concepts in Hinduism involve a belief in a divine power that manifests in different forms, notably the trinity of Brahma (the creator), Vishnu (the preserver), and Shiva (the destroyer), which to some extent parallels the concept of the Trinity in Christianity.
