What is the name of the relationship between ∠1 and ∠5?

A) alternate exterior angles

B) corresponding angles

C) alternate interior angles

D) adjacent angles

Two lines are crossed by another line (called Transversal), the angles in matching corners are called corresponding angles. There are two parallel lines interest by the Transversal and ∠1 and ∠5 are made on the matching corners. Thus ∠1 and ∠5 are the corresponding angles.
