H 2 O has two lone pairs of electrons on oxygen atom. while SO 2 has one lone pair of electron. Both possess bent shape as shown below:

Due to l p-lp repulsion, it has bent shape.

Due to l p-b p repulsion it has bent shape. Thus, A is correct but R is incorrect.

Q. Assertion (A) The structure of $H_{2} O$ is similar to $S O_{2}$ .
Reason (R) In both molecules $(H_{2} O$ and $S O_{2})$ , the central atom has one lone pair of electrons.

Both $A$ and $R$ are correct; $R$ is the correct explanation of $A$ .

Both $A$ and $R$ are correct; $R$ is not the correct explanation of $A$ .

$A$ is correct; $R$ is incorrect.

$A$ is incorrect; $R$ is correct.

$H_{2} O$ has two lone pairs of electrons on oxygen atom. while $S O_{2}$ has one lone pair of electron.
Both possess bent shape as shown below :

Due to $lp$ -lp repulsion, it has bent shape.

Due to $lp - b p$ repulsion it has bent shape. Thus, $A$ is correct but $R$ is incorrect.
