Answer:

Assertion (A) is true

but reason (R) is false.

Explanation:

If we look at the assertion closely, it is true that a sublime substance changes from solid to gas without  passing through a liquid state. Naphthalene, camphor, iodine and ammonium  chloride are some common  examples of the substances  which undergo sublimation.

However, not all solids first pass through a liquid state before converting to gas. Sublime solids such as those listed above passes directly from solid to gas without passing through a liquid state.

Hence the assertion is true but reason is false.
