Assertion (A): Derived units are expressed as combinations of base units.
Reason (R): Magnitudes of physical quantities with different dimensions can be added together.

Both A and R are true but R does not explain A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
