Correct answer: B. Buddha Dhamma Sangha
Explanation: The governing concept is the Buddhist refuge formula known as the Three Jewels or Triple Gem. Buddhists traditionally take refuge in the Buddha, the awakened teacher; the Dhamma, the teaching and path; and the Sangha, the community that preserves and practises that teaching. Thus option B is correct. Option A refers to the Three Jewels of Jainism, usually expressed as right faith, right knowledge, and right conduct, so it is a useful but deliberate distractor. Option C names important Brahmanical texts, not the Buddhist Triple Gem, and option D names three South Indian dynasties.
