Check my answer in bold .

the following is an incomplete paragraph proving that ∠wrs ≅ ∠vqt, given the information in the figure where segment uv is parallel to segment wz.:

according to the given information, segment uv is parallel to segment wz while angles squ and vqt are vertical angles. by the vertical angles theorem. because angles squ and wrs are corresponding angles, they are congruent according to the corresponding angles postulate. finally, angle vqt is congruent to angle wrs by the transitive property of equality.

which phrase accurately completes the proof?

select one:
a. ∠squ ≅ ∠vqt
b. ∠squ ≅ ∠wrs
c. ∠wrs ≅ ∠vqt
d. ∠wrs ≅ ∠zrt
