Correct answer is (a) True

Explanation: Due to a capacitive load, armature current is in opposite and 90° phase with the field magneto-motive force. Armature magneto-motive force produced due to this current will be in 180° phase and 90° phase with the field flux. The nature of the armature reaction is partially demagnetizing and cross magnetizing.
