Answer:
Option B. ∠K≅∠A
Explanation:
we know that
If two triangles are congruent, then the corresponding angles and the corresponding sides are congruent
In this problem
Triangles KQB and AQB are congruent by SAS postulate
Remember that
The Side Angle Side postulate (SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent
therefore
∠K≅∠A ----> corresponding angles are congruent
