Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
$H_{2} S O_{4}$ in more viscous than water because in $H_{2} S O_{4}$ , due to hydrogen bonding, several molecules bind together to form a cluster. Sulphur has highest oxidation state (+6) in $H_{2} S O_{4}$ . Hence, both assertion and reason are correct but reason is not the correct explanation for assertion.
