Question 292 of 412

If L, C and R denote the inductance, capacitance and resistance respectively, the dimensional formula for C²LR is 

(1) $\left[M{L}^{-2}{T}^{-1}{I}^0\right]$

(2) $\left[M^0{L}^0{T}^3{I}^0\right]$

(3) $\left[M^{-1}{L}^{-2}{T}^6{I}^2\right]$

(4) $\left[M^0{L}^0{T}^2{I}^0\right]$
