Which of the following is not a unit of time?

Options

  1. ALunar month
  2. BLight year
  3. CLeap year
  4. DMicrosecond

Correct answer

B. Light year

Step-by-step solution

A light-year is a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9 . 4607 × 10 12   km (nearly six million miles). Hence, Light-year is a unit of distance not time.
