B ⊂ A.
Reason: every triangle is a polygon, so B (triangles) is a subset of A (polygons). A ⊂ B is false because there are polygons that are not triangles (e.g. squares). Ac = B and Bc = A are false (their complements would be sets of non-polygons/non-triangles, not the other given sets), unless a very unusual universal set were specified.
