[A] Only one

[B] Only two

[C] All three

[D] None

Answer: B

Notes:

Explanation:

Pair 1: Incorrect. While Brahmagupta (Brahma Sphuta Siddhanta) was a major figure in Astronomy, Aryabhata (who calculated the solar year at 365.258 days) and Varahamihira were also key figures. Brahmagupta’s work mainly focuses on Mathematics (Zero properties) and Astronomy.
Pair 2: Correct. Bhaskaracharya (Bhaskara II) wrote Siddhanta Shiromani (12th century), which contains the Lilavati (Maths) and Bijaganita (Algebra) and famously touched upon the concept of differential calculus (known as Tatkalika Gati).
Pair 3: Correct. Vagbhata (c. 6th–7th century AD) is considered one of the three great authorities of Ayurveda (Trinath), and his work, Ashtanga Hridaya Samhita, is a crucial compendium.
