Which of these diagrams shows a pair of vertical angles?

Three points connected by line segments converging at a central point, pointing in different directions. The middle segment, in conjunction with the outer segments, forms two distinct angles at the junction where the segments meet. These angles are shaded for emphasis: one in green and the other in red, to indicate their difference.

A

Two intersecting lines creating congruent angles, highlighted by identical shading.

B

Four line segemnts were drawn from four distinct points to a common point creating four distinct angles. One angle is shaded red and the other is shaded purple signifying that their measures are not congruent.

C

Two intersecting lines creating two pairs of two congruent angles. The pair with a bigger angle has one angle shaded in green, the pair with a smaller angle has one angle shaded in blue.
