Question

Which one of the following is not a fundamental SI unit?

• A. Ampere
• B. Candela
• C. Newton
• D. Kelvin

Answer 1

The correct option is C

Newton

(1) A fundamental unit is a measurement unit used to measure a base quantity.

(2) The fundamental unit for a certain measurable quantity is chosen.

(3)Kilogram, meter, candela, second, ampere, kelvin, and mole are the seven fundamental units in the SI system.

(4) The second represents time, the meter represents length or distance, the kilogram represents mass, the ampere represents electric current, the kelvin represents thermodynamic temperature, the mole represents the amount of substance, and the candela represents luminous intensity.

So, clearly, newton is not a fundamental SI unit.

Hence option C is the correct answer.
