I'm thinking that the answer to this question is 4, but I don't know whether it is truly that simple.

I know that a reflexive relation, R, occurs when for all x in A, x R x.

so let's say A = {1,2,3,4}.

1~1

2~2

3~3

4~4.

So there are 4 "relations" here. I believe the answer to this is 4, *or* it could be 1 as A~A. Is it right?
