Verified by Experts
The correct answer is:
D
Step 1: Understand the difference between base and derived units.
Base units are fundamental units defined by specific physical measurements, such as kilogram (mass), meter (length), and second (time).
Step 2: Identify the units from the options provided:
  • Option A: Unit of mass - This refers to the kilogram, which is a base unit.
  • Option B: Unit of length - This refers to the meter, which is also a base unit.
  • Option C: Unit of time - This refers to the second, another base unit.
  • Option D: Unit of volume - Volume is not a fundamental measure on its own; it is derived from the base units of length (e.g., cubic meter).
Step 3: Conclude that a derived unit is one that is derived from base units. Therefore, since volume (e.g., cubic meter) is derived from the base unit of length,
Thus, the correct answer is D.
