"Right Belief, Right Knowledge and Right Action" are the three jewels of which religion?

Jainism

The correct answer is Option (2) - Jainism

In Jainism the three jewels (also referred to as ratnatraya) are understood as samyagdarshana (“right faith”), samyagjnana (“right knowledge”), and samyakcharitra (“right conduct”). One of the three cannot exist exclusive of the others, and all are required for spiritual liberation.
