Final answer:
A reflection cannot map trapezoid 1 to trapezoid 2.
Step-by-step explanation:
In order for a transformation to map trapezoid 1 to trapezoid 2, the two trapezoids must have corresponding sides and angles. A rotation can map the trapezoids if the angles and sides are preserved. A translation can also map the trapezoids if the sides are parallel and the same length. However, a reflection cannot map the trapezoids because the corresponding sides and angles would not be preserved. Therefore, the correct answer is C. Reflection.
