Answer: C. ∠4 and ∠5
Step-by-step explanation:
When two lines intersects , then they form two pair of vertically opposite angles.
In the given figure, we two lines intersecting each other.
Also, The pair of vertical angles are:
∠2 and ∠3 ; ∠4 and ∠5
We know that the vertically opposite angles are congruent.
Then , the pair of congruent angles :
∠2 and ∠3 ; ∠4 and ∠5
Hence, C is the correct option.
