As I go through mock exam questions in preparation for my imminent test I am just getting confused on things that I thought were clear. I’m finding the explanations to different questions explain  different responses to essentially the same situation.  Here is one situation on which I would appreciate advice. The question is an amalgamation of several questions to bring out the relevant options , and I don’t know the true answer since I have seen at least 3 different answers provided as the correct answer.
