Answer: The correct option is:
(D) It is a trapezoid because it has exactly one pair of opposite sides that is parallel.
Step-by-step explanation: We are given to select the statement that best describes the structure outlined in the bridge.
The definitions of a parallelogram and a trapezoid are as follows:
PARALLELOGRAM: A Parallelogram is a quadrilateral having opposite sides parallel and congruent.
TRAPEZOID: A trapezoid is a quadrilateral having one pair of opposite sides parallel.
We can see in the given figure,
the structure outlined in the bridge has only one pair of opposite sides parallel.
So, it must be a TRAPEZOID.
Therefore, the given structure is a trapezoid because it has exactly one pair of opposite sides that is parallel.
Thus, (D) is the correct option.
