STATEMENT-1: The conversion of fresh precipitate to colloidal state is called peptization.
STATEMENT-2: It is caused by addition of common ions.

A

If both assertion and reason are ture, and reason is the trure explanation of the assertion.

B

If both assertion and reason are true, but reason is not the true explanation of the assertion.

C

If assertion is true, but reason is false.
