The correct option is A Vardhamana Mahavira
Vardhamana Mahavira was born in a Ganasangha. He left his family and home at the age of 30 years, and became a Parivrajaka. He was seeking an answer to the question, How can we get rid of the cycle of birth and death in this world? After years of meditation and hard penance, Mahavira finally found an answer to his question. Mahavira kept wandering for spreading his teachings among the people. A large number of people began to follow his preaching. Thus began Jainism.
