Hint: Quantities which can be measured or quantified are known as Physical quantities. Fundamental quantities are the basic quantities which does not depend on any other physical quantity. These quantities are essential to form all the other physical quantities apart from fundamental quantities. Quantities which are formed using these fundamental quantities are called Derived quantities.
Complete answer:
Physical quantity is the property of a substance or a material which can be measured or quantified by measurement. There are two types of physical quantities namely, fundamental quantities and derived quantities.
The physical quantities which do not depend upon any other quantities are known as Fundamental quantities. There are seven fundamental quantities which are:
1) Length
2) Mass
3) Time
4) Electric current
5) Thermodynamic temperature
6) Amount of substance
7) Luminous intensity.
All the other quantities formed using these seven quantities are called Derived quantities. Examples of derived quantities are area, volume, work, speed, etc. Work depends on fundamental quantities like length, mass and time and hence it is a derived quantity. Thus, work is not a fundamental quantity.
Hence, the correct answer is option D i.e. work.
Note:
Students should remember the seven fundamental quantities and the derived quantities to answer such types of questions. Dimensions of a physical quantity tells us how that quantity depends on the various fundamental quantities. Fundamental quantities and derived quantities have their respective units known as fundamental units and derived units. Examples of fundamental units are meter, kilogram, Kelvin, etc. Examples of derived units include Newton, Joule, Volt etc.
