Option 3 : The efficiency of the lap winding is less

Differences Between Lap and Wave Winding:

In lap winding the number of parallel paths is equal to the total number of poles of the coil and in wave winding the number of parallel paths is always equal to two.
The lap winding is also called parallel winding because the coils are connected in parallel whereas in the wave winding the coils are connected in series hence it is called series winding.
The EMF of the lap winding is less as compared to wave winding.
The lap winding requires an equalizer for better commutation. The wave winding requires the dummy coil for giving the mechanical balance to the armature.
In lap winding, the number of brushes is equal to the number of parallel paths whereas in wave winding the number of brushes is two.
The efficiency of the lap winding is less compared to the wave winding.
