If product is oxy acid with $-ic$ suffix

(A) The reaction is: $\underline{Si}H_4 + 4H_2O \longrightarrow H_4SiO_4 + 4H_2$. $H_4SiO_4$ is also written as $Si(OH)_4$ or $H_2SiO_3 \cdot H_2O$,which is silicic acid. In silicic acid,the oxidation state of $Si$ is $+4$. Since the maximum oxidation state of $Si$ is $+4$,the acid is named with the $-ic$ suffix (silicic acid). Therefore,the product is an oxy acid with an $-ic$ suffix.
