Referring to the illustration of a twin-screw diesel-electric AC propulsion drive system, if either the port propulsion excitation transformer or the port propulsion field controller was inoperable, what statement is true? Illustration EL-0164
A
The standby excitation transformer and standby field controller could be used to control the field of the port propulsion motor, and this would be the only means of backup.
B
The port propulsion drive motor would be inoperable, as no means of field control is provided as a backup.
C
The starboard excitation transformer and starboard field controller could be used to control the field of the port propulsion motor, and this would be the only means of backup.
D
