There are two statements, one labelled as Assertion
(A) and the other as Reason (R). Examine both the statements carefully and mark the correct choice.
(A) The $\mathrm{O}-\mathrm{H}$ bond angle in ${\mathrm{H}}_2\mathrm{O}$ is greater than $\mathrm{S}-\mathrm{H}$ bond angle in ${\mathrm{H}}_2\mathrm{S}.$
(R) Due to larger size of $\mathrm{S}$, hydrogen bonding does not occur in ${\mathrm{H}}_2\mathrm{S}.$
