The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Initially, like the Buddhists, the Jainas were not image worshipers. Later they began to worship Mahavira and also the twenty-three tirthankaras. Beautiful and sometimes massive images in stone were sculpted for this purpose, especially, in Karnataka, Gujarat, Rajasthan, and Madhya Pradesh. Here both the assertion and the reason are correct but the reason is not the correct explanation for assertion. So the correct option is B.
