"a quadrilateral is a trapezoid if and only if it has exactly one pair of parallel sides."

if this statement is true, then which of the following statements must also be true?

a. a trapezoid has exactly one pair of parallel sides if and only if it is a quadrilateral.
b. a quadrilateral has exactly one pair of parallel sides if and only if it is a trapezoid.
c. a quadrilateral is not a trapezoid if and only if it has exactly one pair of parallel sides.
d. a quadrilateral does not have exactly one pair of parallel sides if and only if it is a trapezoid.

The given statement about Trapezoid is

 "A quadrilateral is a trapezoid if and only if it has exactly one pair of parallel sides."

Other Quadrilaterals, Parallelogram, Rhombus, Square, Rectangle and Kite can be also Called as Trapezoid.
