Question

3.What was kanta doing​

Answer 1

Karna had the chariot of Lord Parasurama, white horses (probably Gandharava horses) but he didn't used them until 17th day. Arjuna had the chariot of Lord Agni and Gandharva horses which he used from the event of Khandava Forest event. ... It was Arjuna again who requested Krishna to become his charioteer.

Ur Question is wrong.

It will be

What was Karna doing?

not kanta.
