The SI unit of a physical quantity is Pascal-sec. The dimensional formula of this quantity will be
Answer: (C) $[\text{ML}^{-1}\text{T}^{-1}]$
Pascal is pressure: $[\text{ML}^{-1}\text{T}^{-2}]$. Multiplying by time:
$$[\text{ML}^{-1}\text{T}^{-2}][\text{T}] = [\text{ML}^{-1}\text{T}^{-1}]$$
(This is the unit of the coefficient of viscosity.)
