Answer:
Option A
Step-by-step explanation:
Angles 3 and 6 are vertical angles, located opposite to each other.
Angles 2 and 11 are NOT corresponding angles; they are not on the same side of one of two lines cut by a transversal.
Angles 4 and 14 are NOT alternate interior angles because angle 4 lies on transversal s and line l, and angles 14 lies on transversal t and line m.
Angles 7 and 14 are NOT complementary angles because both angles add up to 180 degrees, not 90 degrees.
I hope this question is now clear to you.
