Match the following columns.

Column I (A) R/L (B) CR (C) E/B $\text{ (D) }\sqrt{{\epsilon }_0{\mu }_0}$

Column II (p) Time (q) Frequency (r) Speed (s) None

$\mathrm{A}\to \mathrm{q};\mathrm{B}\to \mathrm{p};\mathrm{C}\to \mathrm{r};\mathrm{D}\to \mathrm{s}$

$\text{ (A) }\left[R\right]/\left[L\right]=\frac{\left[M{L}^2{T}^{-3}{A}^{-2}\right]}{\left[M{L}^2{\Gamma }^{-2}{A}^{-2}\right]}=[T{]}^{-1}$

        This is the dimensions of frequency.

         $\left(A\right)\to \left(q\right)$

  (B)  $\left[\mathrm{CR}\right]=\left[{\mathrm{M}}^{-1}{ \mathrm{L}}^{-2}{ \mathrm{T}}^4{ \mathrm{A}}^2\right]\left[{\mathrm{ML}}^2{ \mathrm{T}}^{-3}{ \mathrm{A}}^{-2}\right]=\left[\mathrm{T}\right]$

         This matches with the dimensions of time given in the column,
         (B) $\to$ (p)

$\text{ (C) }\left[\mathrm{E}\right]/\left[\mathrm{B}\right]=\frac{\left[{\mathrm{MLT}}^{-3} {\mathrm{A}}^{-1}\right]}{\left[{\mathrm{MT}}^{-2}{ \mathrm{A}}^{-1}\right]}=\left[{\mathrm{LT}}^{-1}\right]$

       This is the dimensions of speed. 
        (C) $\to$(r)

$\text{ (D) }{\left[{\epsilon }_0{\mu }_0\right]}^{1/2}={\left\{\left[{\mathrm{M}}^{-1}{ \mathrm{L}}^{-3}{ \mathrm{T}}^4{ \mathrm{A}}^2\right]\left[{\mathrm{MLT}}^{-2}{ \mathrm{A}}^{-2}\right]\right\}}^{1/2}={\left[{\mathrm{L}}^{-2}{ \mathrm{T}}^2\right]}^{1/2}=\left[{\mathrm{L}}^{-1} \mathrm{T}\right]$

       This does not matches with the dimensions given in the column,
       (D) $\to$ (s)
