After an aeroplane completes a voyage, its muzzle feels warmer than the middle and back portion of the main body. This is because:

the muzzle tears apart the air layers and suffers more air friction

Solution

The correct option is A the muzzle tears apart the air layers and suffers more air friction
Aeroplanes are given streamline shapes. Due to this special shape, the muzzle tears apart the air layers faced while the plane is in motion. So, the muzzle encounters more air friction and becomes warmer.
