Out of the following pair, which one does NOT have identical dimensions is

Correctt option is C) moment of inertia and moment of a force

Moment of inertia, I = Mr^{2} \( \therefore\) [I] = [ML^{2}] Moment of force, \(\overrightarrow \tau = \overrightarrow r \times \overrightarrow F \) \(\therefore[\overrightarrow \tau ]=[L][ML{T^{ - 2}}]=[ML^{ 2}{T^{ - 2}}]\)
