D. ASA

Step-by-step explanation:

In the figures given,

<A and <B in ∆ABC are congruent to corresponding angles <X and <Y in ∆XYZ in ∆XYZ.

Also, an included side AB in ∆ABC is congruent to a corresponding included side XY in ∆XYZ.

According to the ASA triangular theorem, two ∆s are congruent to each other when they have two corresponding angles in each of the triangles that are congruent to each other and an included side that is also congruent to each other.

Therefore, ∆ABC is congruent to ∆XYZ based on the ASA theorem.
