Answer:

Technician A is correct.

Explanation:

                           A clutch is mechanical device that is used to engaged and disengaged with the engine flywheel and the gear box.  It is operated by pressing the clutch pedal of the vehicle and it helps in disengaging the clutch. While releasing the clutch pedal, the clutch is engaged to the flywheel and it helps in transmission.

                         Thus during hard acceleration of the vehicle, it is quite obvious that the clutch may slip form the flywheel and will decrease its efficiency.

Thus the answer is  Technician A is correct.
