The most appropriate answer is A, the the start winding on a split-phase motor is to provide a starting torque. A split-phase motor is a single phase electrical motor (common in many household applications such as washing machines and household fans), with two distinct windings on the stator coils, the start windings and the run windings, at 90 degrees apart. When the motor is energised the start coils acts like a second phase (2 phase motor) and helps provide the rotating magnetic field that is necessary to turn the rotor. Once moving, only the run winding (single phase) is required to keep the motor spinning.

The other answers are irrelevant for the starting of the motor.

What is pure carbon made of
DerKrebs [107]

Answer: Both diamond and graphite are made entirely out of carbon, as is the more recently discovered buckminsterfullerene (a discrete soccer-ball-shaped molecule containing carbon 60 atoms). The way the carbon atoms are arranged in space, however, is different for the three materials, making them allotropes of carbon. (My Notes)
