Whose name is this? - Page 30

Correct!

91. Who was called Rauhiṇeya?

Again taking a guess,

Balarama, son of Rohini

Correct!

92. Whose name was Pavanātmaja?

Correct!

93. Who was called Kalaśottamasaṃbhava, Kumbhasaṃbhava, and Kumbhayoni?

The Kauravas? Since they were born after gestation in earthen pots?

Clever guess, but the Dhārtarāṣṭras are not called by these names in the text.

The word used for the vessels in which they gestated is kuṇḍa - not kumbha or kalaśa. It could mean a pit rather than a pot.

Dronacharya then

Agastya (idk if he's mentioned in Mahabharata)

Droṇa is correct for all three names: Kalaśottamasaṃbhava, Kumbhasaṃbhava, and Kumbhayoni.

Agastya's story is told in Āraṇyakaparvan, where he is called Kumbhayoni, so that answer is also correct.

94. Whose name was Śaiśupāli?

Dhṛṣtaketu son of Shishupal

Correct!

95. Whose name was Vārṣṇeya?
