Abhimanyu is the son of Bhima
B
Correct answer
Explanation
Abhimanyu was the son of Arjuna and Subhadra, making him Arjuna's son, not Bhima's. He was a key warrior in the Mahabharata war who famously entered the Chakravyuha formation but was trapped and killed by the Kaurava warriors, as he only knew how to enter but not exit the formation.
