✝️ Correct answer is Work. Option D

Fundamental quantities are those physical quantities that cannot be expressed in terms other quantities. It is independent on its own. For example: Mass, Length, time, temperature, electric current.

Work is an Derived quantity which depends on Force and distance in terms of laws of motion and Potential difference and Charge in Electricity. Hence, it is odd.

⏭SI base units

The SI is founded on seven SI base units for seven base quantities assumed to be mutually independent, these are known as Fundamental Quantities.

⏭SI derived units

Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units.
