Idea: look first at whether the output changes when only one input changes.
Comparing the rows 00 and 10, A has changed while Y has not; the same holds for 01 and 11.
So Y does not depend on A at all, and every expression containing A can be set aside.
What remains is the relation between B and Y: B=0 gives Y=1 and B=1 gives Y=0.
That is Y=B.
