Solution

The correct option is A Assertion and reason both are correct statements and reason is the correct explanation for assertion.
An ionic crystal consists of ions(cations and anions) bound together by strong electrostatic attraction. Because of these strong electrostatic forces of attraction between cation and anion, ionic solids exist as hard solids at room temperature. Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
