Official USCG Answer & Rule Citation

Correct Answer: Option B — series wound

Series wound DC motors feature field windings in series with the armature, drawing maximum starting current through both. This creates the highest starting torque, making them ideal for heavy starting applications like deck winches and capstans under Title 46 CFR and IEEE 45 standards.
