Question

Find the odd pair : Ampere - A , Kelvin - k , Metre -M , Candela - Cd​

Answer 1

Answer: Kelvin (k)

Ampere (A) is the SI unit of the fundamental quantity of current

Kelvin (K) is the SI unit of the fundamental quantity of temperature

Metre (M) is the SI unit of the fundamental quantity of length

Candela (Cd) is the SI unit of the fundamental quantity of luminous intensity

All four of these are part of the seven fundamental quantities under the SI system of units.

But Kelvin is denoted by a capital K, not a small k. A small k is usually used to denote the Coulomb constant or the Boltzmann Constant.
