Fundamental units in MKS system are:
Correct answer: D. Kilogram, meter and second
- A. Gram, dyne and second
- B. Kilogram, centimetre and second
- C. Kilogram, Newton and second
- D. Kilogram, meter and second
Explanation
D is the correct answer. In the MKS system, the kilogram is the unit of mass, the meter is the unit of length, and the second is the unit of time. These three fundamental units provide the basis for measuring other physical quantities in a coherent and consistent manner.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
