Actually I think I was wrong about the cloudbase. The 3000ft RPS thing is a trap answer for an obviously different reason!
When marking a question like this, I discuss the answer with the applicant afterwards (if he's passed) - to point out the impractical nature of the 'correct' answer and to elicit his/her understanding of the options given.
One option, which is supposedly the correct one, also causes the aircraft to manoeuvre close to the instrument approach route for a nearby civil aerodrome. Not a good idea, in my opinion.
'tis a most silly question for a black-and-white answer.
