The correct answer is: A. Two phase induction motor.

A two-phase induction motor is a type of AC motor that uses two windings to create a rotating magnetic field. The stator windings are arranged so that they are 90 degrees apart, and the current in each winding is out of phase with the current in the other winding. This creates a rotating magnetic field that causes the rotor to turn.

A three-phase induction motor is similar to a two-phase induction motor, but it has three windings instead of two. The windings are arranged so that they are 120 degrees apart, and the current in each winding is out of phase with the current in the other windings. This creates a stronger rotating magnetic field that causes the rotor to turn faster.

A direct current series motor is a type of DC motor that has the field winding and the armature winding connected in series. This means that the current flows through both windings in the same direction. The field winding creates a magnetic field that causes the armature to turn. The armature winding is connected to the commutator, which reverses the current direction in the armature winding every time the rotor turns halfway around. This causes the rotor to continue turning in the same direction.

A universal motor is a type of motor that can be powered by either AC or DC. It has a stator winding and an armature winding, like a DC motor. However, the field winding is connected to the armature winding through a commutator. This allows the motor to operate on either AC or DC.

In conclusion, the correct answer is: A. Two phase induction motor.
