I'd say D, since port tack will carry you away from the shoal, even if you can't point higher than south (but southeast would be better).
A only works if I'm making headway. If hove-to, maybe I'm not.
B is stupid, unless I have an engine. Do I? Even if I do, striking all sails will give a horrible unsteadied ride.
c--Strike what
jib? I 've got a staysail up already.
So I'd get onto the tack that tends to set me away from the shoal rather than towards it.
It's too easy to overthink an answer when they don't give you enough info in the question.
Okay, whether I was right or wrong, since it's May 1st, and easy one..
What's the origin of the distress call "Mayday"?
