Solution

The correct option is C $- [- O - (M e)_{2} S i - O -] -_{n}$
Dimethyl dichlorosilane $(M e)_{2} S i C l_{2}$ on hydrolysis will produce $- [- O - (M e)_{2} S i - O -] -_{n}$ which is a thermoplastic polymer.

$H O - M e | S i | M e - \begin{matrix} O H + H \end{matrix} O - M e | S i | M e - O H H - --- \to - H_{2} O O - M e | S i | M e - O - M e | S i | M e - O H P o l y m e r i s a t i o n - ---------- \to {⎡ ⎢ ⎣ - O - M e | S i | M e - O - M e | S i | M e - O - M e | S i | M e - O - ⎤ ⎥ ⎦}_{n}$
Therefore, the correct option is (c).
