Detailed explanation-1: -Among the following quantities, an electric current is a fundamental quantity whereas gravitational constant, frequency and electric charge are the derived quantities.
Detailed explanation-2: -Derived quantities are quantities that are calculated from two or more measurements. Three examples are area, volume, and density. The area of a surface is how much space it covers, the volume of a solid is how much space it takes up, and the density of an object is how much matter is packed into a given space.
Detailed explanation-3: -Answer: Any 5 derived units are velocity, power, energy, force and density.
Detailed explanation-4: -Hence option B is correct, the height of a room is the only quantity that is not a derived quantity.
