JEE Math Practice Question

Let $$A$$ be a matrix such that $$A.\left[ {\begin{matrix} 1 & 2 \\ 0 & 3 \\ \end{matrix} } \right]$$ is a scalar matrix and |3A| = 108. Then A2 equals :

1. A.$$\left[ {\begin{matrix} 4 & { - 32} \\ 0 & {36} \\ \end{matrix} } \right]$$
2. B.$$\left[ {\begin{matrix} {36} & 0 \\ { - 32} & 4 \\ \end{matrix} } \right]$$
3. C.$$\left[ {\begin{matrix} 4 & 0 \\ { - 32} & {36} \\ \end{matrix} } \right]$$
4. D.$$\left[ {\begin{matrix} {36} & { - 32} \\ 0 & 4 \\ \end{matrix} } \right]$$
