The correct answer is option 'D' - Jaw clutch.

Explanation:
A friction clutch is a type of clutch that uses friction to transmit power between two rotating shafts. It consists of two plates or discs that are pressed together, creating friction and allowing the power to be transferred from one shaft to another.

Let's discuss each option and why it is or is not a friction clutch:

a) Disc or Plate Clutch:
A disc or plate clutch is a type of friction clutch. It consists of a friction disc or plate that is pressed against another disc or plate to transmit power. This type of clutch is commonly used in automobiles.

b) Cone Clutch:
A cone clutch is also a type of friction clutch. It consists of two cones, one of which is connected to the driving shaft and the other to the driven shaft. When the two cones are pressed together, friction is generated, allowing the power to be transmitted.

c) Centrifugal Clutch:
A centrifugal clutch is not a friction clutch. It operates based on centrifugal force. It consists of weighted arms or shoes that are forced outward by centrifugal force as the speed of the driving shaft increases. This causes the clutch to engage and transmit power.

d) Jaw Clutch:
A jaw clutch is also not a friction clutch. It is a type of positive clutch that relies on the mechanical engagement of interlocking jaws or teeth. When the jaws or teeth of the driving and driven members interlock, power is transmitted. It does not rely on friction for power transmission.

In summary, all options except for option 'D' (Jaw clutch) are friction clutches. A jaw clutch is a type of positive clutch that operates based on the mechanical engagement of interlocking jaws or teeth.
