We know that "a quadrilateral has four sides."

A parallelogram is a kind of quadrilateral with opposite sides are parallel.

So statement A is always true.

A trapezoid is a kind of quadrilateral with two parallel and two non-parallel sides, thus it never be parallelogram, thus statement B is never true.
