to which parva of mahabharat does gita belong
Bhishma Parva This book of Mahabharata includes the widely studied Bhagavad gita, sometimes referred to as Gita, or The Song of the Lord, or The Celestial Song. Bhagavadgita chapters describe Arjuna's questioning the purpose of war, ultimate effects of violence and the meaning of life.[7][8] Arjuna's doubts and metaphysical questions are answered by Krishna.[9] Other treatises in Bhishma parva include the Just war theory in ancient India,[10] as well as strategies of war and troop deployment.This book describes the deaths of Uttarā kumarā (brother-in-law of Abhimanyu and brother of Uttara wife of Abhimanyu), Vrishasena (Elder son of Karna) and also Bhishma's fall respectively on 1st, 3rd and 10th days of the war. Karna didn't fought in these first ten days on Bhishma's order.
Vikarna In the Hindu epic Mahabharata, Vikarna (Sanskrit-विकर्ण) (Tamil: விகர்ணன்) (Telugu: వికర్ణుడు) (Kannada: ವಿಕರ್ಣ) is a Kaurava, a son of Dhritarashtra and Gandhari and a brother to the crown prince Duryodhana. Vikarna is universally referred to as the third-most reputable of Kauravas. Usually, he is also indicated as the third-oldest son, but in other sources, the "third-strongest" reputation remained and it is implied that Vikarna is just one of Gandhari's 99 children (after Duryodhana and Dussasana). Vikarna was the only Kaurava who questioned the humiliation of Draupadi, the wife of his cousin Pandavas, after they lost her in a game of dice to Duryodhana.
