Correct answer is (a): physics
Explanation:
· Subrahmanyam Chandrasekhar, an Indian-American astrophysicist, was awarded the Nobel Prize in Physics in 1983.
· He received the prize jointly with William A. Fowler "for his theoretical studies of the physical processes of importance to the structure and evolution of the stars."
Information Booster:
· Chandrasekhar is famous for his work on the Chandrasekhar limit, which defines the maximum mass (approximately $1.4$ times the mass of the Sun) a stable white dwarf star can have.  If a star's core exceeds this limit after exhausting its nuclear fuel, it will collapse into a neutron star or a black hole.
· He was the nephew of Sir C. V. Raman, who also won the Nobel Prize in Physics in 1930.
