The correct answer is A. follow three jewels and five vows.
The three jewels of Jainism are right faith, right knowledge, and right conduct. The five vows are non-violence, non-stealing, non-attachment, non-lying, and non-possession.
Right faith is the belief in the teachings of Jainism. Right knowledge is the understanding of the true nature of reality. Right conduct is the practice of the five vows.
Non-violence is the most important vow in Jainism. It means avoiding all harm to living beings, including insects. Non-stealing means not taking anything that does not belong to you. Non-attachment means not being attached to material possessions or worldly desires. Non-lying means telling the truth at all times. Non-possession means not owning more than you need.
By following the three jewels and five vows, Jains believe that they can attain Nirvana, or Moksha, which is a state of perfect peace and liberation from suffering.
Option B is incorrect because it does not mention the three jewels. Option C is incorrect because it does not mention the five vows. Option D is incorrect because it does not mention the three jewels or the five vows.
