Solution

The correct option is C Assertion is correct but Reason is incorrect
Special methods are required to prepare lyophobic sols and additional stabilizers are required during their preparation as they are not solvenrt loving as lyophilic sols, lyophilic sols are relatively stable as strong forces of interaction exits between particles.

Hence Assertion is true but Reason is false.
