Correct Answer - Option 3 : Newton

Concept:

• Fundamental Quantity: An independent Physical Quantity that cannot be expressed in terms of other Physical Quantities is called fundamental quantity.
• They are conventionally chosen. It is used as a base to get other derived quantities by combining them.
• Fundamental unit: The SI unit of a fundamental quantity is called a fundamental unit.
• There are 7 fundamental quantities and their fundamental units.
• The fundamental Quantities are Length, Mass, Time, Electric Current, Thermodynamic Temperature, Luminous intensity, etc.
• ​Supplementary units:  The units that are used along with base units to form derived units in the International System are called supplementary units.
 Fundamental Quantities Quantities S.I unit Mass Kilogram(kg) Length meter(m) Time second(s) Amount of Substance Mole(mol) Temperature Kelvin(K) Electric Current Ampere(A) Luminous intensity Candela(cd) Supplementary Quantities Plane angle radian(rad) Solid angle steradian(Sr) Derived Quantities Force Newton(N) Work Joule(J), calorie Pressure Pascal(Pa) Power Watt(W)

Explanation:

• Newton is not a fundamental unit it is a Derived S.I unit.

So option Newton  is correct.
