Answer:
<h2>B. Reflection</h2>
Step-by-step explanation:
If we apply a glide reflection to quadrilateral A, we will obtain quadrilateral B.
If you observe carefully, the quadrilateral didn't change its size, this means the transformation only includes movement, not stretching or widening.
Now, there's a glide reflection, because this involves a rotation and translation, and you can see the figure where rotated and translated, so there was applied a glide reflection, which is a specific type of reflection.
Therefore, the right answer is B.
