In K. C. Jain’s reconstruction of Mahavira’s birthplace, Kundapura was near which ancient city?

Explanation

Vaishali. K. C. Jain locates ancient Kundapura, also called Kundagrama, near Vaishali after examining Jain scriptural references. Later identifications of Mahavira’s birthplace differ, so this question specifies the scholarly account rather than treating every identification as settled.
