Elementary Category Theory

Recently I started learning CT, and I'm trying to express the property "set A is contained within set B" (in the Set Category) using CT language only, but I'm quite stuck.

This bothers me for some time now, so I was wondering if someone here has any leads?

Thanks in advance!
