A transversal intersecting two lines creates eight different angles: _____ pairs of corresponding angles, _____ pairs of alternate interior angles,and _____ pairs of alternate exterior angles.

At the two intersections, there are four corresponding angle pairs, one for each matching position. The angles between the lines form two alternate interior pairs, and the angles outside the lines form two alternate exterior pairs, so the correct choice is B: 4, 2, 2.
