(D) When $ZnCl_2 \cdot 2H_2O$ is heated strongly,it undergoes hydrolysis due to the presence of water of crystallization.The reaction is as follows:$ZnCl_2 \cdot 2H_2O \xrightarrow{\Delta} Zn(OH)Cl + HCl + H_2O$Further heating of $Zn(OH)Cl$ leads to the formation of zinc oxide $(ZnO)$:$2Zn(OH)Cl \xrightarrow{\Delta} ZnO + ZnCl_2 + H_2O$However,in the context of standard chemistry problems regarding the dehydration of hydrated metal chlorides,the primary product formed upon strong heating is $ZnO$.
