- C. Vessel A is operating astern propulsion; Vessel B shall sound three short blasts.
- D. Vessel A intends to overtake Vessel B on her starboard side; Vessel B shall sound one short blast if in agreement.
Why B is correct
Under 33 CFR §83.34(a)(i)(1), one short blast means 'I intend to leave you on my port side.' Per §83.34(a)(ii), if in agreement, the other vessel shall sound the same signal — one short blast — and take steps to effect a safe passing. Option D describes the overtaking signal context under §83.34(c).
