13. A synchronous machine is run as an unloaded motor. If a low voltage is supplied at the rated frequency, and if the full-load armature current flows, a test is being run to determine the A. windage loss. B. I²R loss. C. stray-load loss. D. core loss. Note: I have doubts if it is the letter A or the letter B, can you help me in this question, thanks.

A freewheeling DC motor is driven with 1000 rpm and a nominal load torque of 80Nm. The field circuit resistance is 200 and the armature circuit resistance is 0.2 O. The field coils are fed with a zero degree transmission angle through a single-phase fully controlled converter connected to a single-phase 240V source. The armature circuit is fed from a single phase 400V source through another fully controlled converter. Magnetic saturation has been neglected, the motor constant is given as 0.8 V - s / A - rad. Assuming that there is no fluctuation in armature and field current, find the control angle of the converter feeding the armature at nominal load.
