Option c is the correct answer. In Jainism, there were twenty-four special leaders called Tirthankaras. The first one was Lord Rishabha, and the last was Lord Mahavira. Mahavira wandered for twelve years to become really wise, and after that, he was called Jina, which means conqueror. People who followed him were called Jains. Important Tips In Jainism, there are three important things to reach salvation: thinking right, knowing right, and doing right. Jain monks were very careful to not hurt anyone, and they didn't like the caste system. Jainism doesn't have a single person who started it. The books that Jains follow also don't say that one person started it. Instead, they believe that this religion has always been there. Jainism got less popular because of its strict rule of not hurting anyone. Farmers had trouble following this rule because they had to kill weeds and bugs to grow their crops.
