Answer: B is not monomer because it generates MeSiOH when subjected to hydrolysis which contains only one reacting site. Hence, the polymerisation reaction stops just after first step.

Answer:
However, Me3SiCl is not a monomer for a high molecular mass silicone polymer as it contains only one Cl atom and at best, it can form a dimer.
