32) A block of mass M  is kept gravity free space and touches the two springs as shown in the figure. Initially springs are in their natural lengths. Now, the block is shifted $({\mathcal{l}}_0/2)$ from the given position in such a way that it compresses a spring and is released. The time - period of oscillation of mass will be.
$$\begin{gathered} \left(A\right) \frac{\mathrm{\pi }}{2}\sqrt{\frac{M}{K}} \\ \left(B\right) 2\mathrm{\pi }\sqrt{\frac{\mathrm{m}}{5\mathrm{K}}} \\ \left(\mathrm{C}\right) \frac{3\mathrm{\pi }}{2}\sqrt{\frac{\mathrm{M}}{\mathrm{K}}} \\ \left(\mathrm{D}\right) \mathrm{\pi }\sqrt{\frac{\mathrm{M}}{2\mathrm{K}}} \end{gathered}$$
