For a given load, the armature current of a synchronous motor will be ...
Since at unity power factor the motor draws no reactive power, the stator current will be minimum.

For a given load, the armature current of a synchronous motor will be ...
Unity power factor:
When the power factor of a synchronous motor is unity, it means that the phase difference between the voltage and current is 0 degrees. This indicates that the motor is operating at maximum efficiency.
Armature current:
The armature current of a synchronous motor is directly proportional to the power factor. As the power factor decreases from unity, the armature current increases. Conversely, as the power factor increases towards unity, the armature current decreases.
Minimum armature current:
For a given load, the armature current of a synchronous motor will be minimum when the power factor is unity. This is because at unity power factor, the motor operates at maximum efficiency, resulting in the lowest armature current for the given load.
Therefore, the correct answer is option 'A' - unity power factor.
