The simplest form of binary relationship is :
a)1:01 am
b)1:N
c)12:01:00 AM
d)recursivE
MY ANSWER IS B ,BUT I AM NOT SURE:)

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. 
thank you so much :)
