The correct reasoning to prove that ∠BQM≅∠BPA is:
Because MN¯¯¯¯¯¯¯¯¯¯ ∥ AC¯¯¯¯¯¯¯¯ and corresponding angles of parallel lines are congruent, ∠BQM≅∠BPA.
This reasoning uses the property that when two lines are parallel, the angles formed with a transversal are congruent, which is the basis for proving that the angles in question are equal.
