The first-section of the Sanskrit Mahabharata is literally known as ______.

Adi-Parvan

The correct answer is Option (3) → Adi-Parvan

"This is an excerpt from the Adi Parvan (literally, the first section) of the Sanskrit Mahabharata, describing why conflicts arose amongst the Kauravas and Pandavas:

The Kauravas were the … sons of Dhritarashtra, and the Pandavas … were their cousins. Since Dhritarashtra was blind, his younger brother Pandu ascended the throne of Hastinapura (see Map 1) … However, after the premature death of Pandu, Dhritarashtra became king, as the royal princes were still very young. As the princes grew up together, the citizens of Hastinapura began to express their preference for the Pandavas, for they were more capable and virtuous than the Kauravas. This made Duryodhana, the eldest of the Kauravas, jealous. He approached his father and said, “You yourself did not receive the throne, although it fell to you, because of your defect. If the Pandava receives the patrimony from Pandu, his son will surely inherit it in turn, and so will his son, and his. We ourselves with our sons shall be excluded from the royal succession and become of slight regard in the eyes of the world, lord of the earth!”"
