The dimensional formula for Boltzmann's constant is

If $A$ and $B$ are two physical quantities having different dimensions then which of the following can't denote a physical quantity?

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$.

Assertion $A$ : Product of Pressure $(P)$ and time $(t)$ has the same dimension as that of coefficient of viscosity.

Reason $R$ : Coefficient of viscosity $=\frac{\text { Force }}{\text { Velocity gradient }}$
