Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-III, B-I, C-II, D-IV
A. A Unit of Length — this matches III. Parsec. A parsec is an astronomical unit of distance, about 3.26 light years.
B. A Unit of Mass — this matches I. Chandrashekar limit. The Chandrasekhar limit, about 1.4 times the mass of the Sun, is the largest mass a white dwarf star can have. It is a quantity of mass, so of the four entries it is the one that goes with mass.
C. A Unit of Time — this matches II. Leap year. A leap year is a year of 366 days, a span of time.
D. A Unit of Work — this matches IV. Joule. The joule is the SI unit of work and energy: the work done when a force of 1 newton moves a body through 1 metre.
