Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Sulphuric acid is more viscous than water because its molecules form hydrogen bonds among themselves. This restricts the movement of the molecules in the liquid, making it highly viscous.

Conc. sulphuric acid is capable of forming hydrogen bonds with water molecules. Thus, conc. sulphuric acid has a high affinity for water.

Although both these statements are correct, the Reason does not give the correct explanation for the Assertion.
