Answer 1

The correct option is A

Temperature

Among the options given, the temperature is a fundamental quantity and it is a measure of the degree of hotness or coldness of a body. It is the degree or intensity of heat present in a substance or object. It is represented according to a comparative scale and is measured by a thermometer. Pressure is derived from force and area. Volume and area are derived from length so these are not fundamental quantities.
