Correct answer: A. Kundagrama
Explanation: The correct answer is Kundagrama, traditionally identified as the birthplace of Vardhamana Mahavira, the twenty-fourth Tirthankara of Jainism. Kundagrama was situated near Vaishali in present-day Bihar, an important region in the religious history of the sixth century BCE. Sarnath is associated with the Buddha’s first sermon, Taxila was a major ancient centre of learning in the northwest, and Ujjain was an important political and commercial city in central India. Therefore, the place-name association in this question clearly points to Kundagrama. The answer should not be confused with Mahavira’s later activities, such as his meditation, preaching, or attainment of liberation.
