Correct Answer: Option D — Relatively low starting torque and relatively low running efficiency

Standard resistive split-phase induction motors inherently produce relatively low starting torque due to minimal phase angle separation, and low running efficiency compared to capacitor-start or polyphase designs, suiting them for light-duty marine auxiliary fans.
