Why C is correct
33 CFR §83.34(a)(ii) states that if a vessel doubts the safety of the proposed maneuver upon hearing a one- or two-blast signal, she shall sound the signal specified in §83.34(d), which is at least five short and rapid blasts. The vessel does not counter-propose with two blasts; doubt requires the danger signal.
