Question

Units of physical quantities can be expressed in terms of fundamental units and such units are called:

• A. Fundamental units
• B. Derived units
• C. Both a and b
• D. None of the above

Answer 1

The correct option is B Derived units

Units of physical quantities can be expressed in terms of fundamental units and such units are called $\text{derived units}$.

Unit of area can be an example for derived unit. If $L$ is the length of the square then $L\times L$ is $L^2$ is its area. Hence, option A is correct.
