For what it's worth, I'd do the one that's easiest. This does assume that you know what the inbound track to the hold is, which side you are to hold and that you have a choice of one of three hold entries. Then, if you do the wrong one (I'd suggest with most examiners, not a fail in itself) you could say, "Well, you are absolutely right, I'll remember your advice for the future!" However, because of the way the hold entries are constructed, you'll probably do the correct one anyway...
