Which of the following is not a unit of time?
- A Lunar month
- B Light year
- C Leap year
- D Microsecond
Answer & Solution
Correct Answer
(B) Light year
Step-by-step Solution
Detailed explanation
A light-year is a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607×1012 km (nearly six million miles). Hence, Light-year is a unit of distance not time.
