b is correct. I do not know where the answers 1:01 am and 12:01:00 AM come in.
recursive is definitely not simple (if it exists).
1:N is a normal relationship. If it were N:N, it has to be broken down into two, namely N:1 and 1:N, with an intermediate column in order that the relationship works properly. U hope this rings a bell to what you've already learned.
