There are mainly two types of clutches:

1. Positive clutches: Positive clutches are used when positive drive is required. Positivedriveis that which provides constant velocity ratio and motion transmission due to successiveengagementanddisengagement.The simplest type of a positive clutch is a jaw or claw clutch. The jaw clutch permits one shaft to drive another through a contact of interlocking jaws.

2. Friction clutches: Such mechanical drive where motion and power transmission occur bymeans of friction. Disc clutches, cone clutch and centrifugal clutches are examples of frictionclutches.

Hence, the correct option is (C).
