Solution

The correct option is D
Assertion is not correct but Reason is correct.

Statement 1: When a crystal is added to a supersaturated solution of itself, it will affect immediate crystallization.
Statement 2: The supersaturated solution is holding more solute than its normal solubility. The excess solute will immediately precipitate out once a crystal is added.
Hence, statement 1 is not correct but Statement 2 is correct.
