Any shape wit four of more sides can have one pair of parallel sides.
Any polygon with four or more sides can have a pair of parallel sides. It is also possible to to have non-polygonal shapes - eg a cigar-shape - that has parallel sides.
A trapezoid has exactly one pair of parallel sides
A parallelogram is an quadrilateral (a figure with four edges and four vertices) with two sets of parallel sides. A trapezoid, also known as a trapezium, is a shape with four sides with a pair of parallel sides.
Any shape with four straight sides is a quadrilateral. A trapezoid has one pair of parallel sides, and a parallelogram has two pairs of parallel sides. So any shape with four straight sides and no parallel sides is a quadrilateral that is not a parallelogram or trapezoid.
Any shape wit four of more sides can have one pair of parallel sides.
A trapezium is a shape with four sides. Of these, one pair of sides are parallel. The only restriction on the other pair is that they are not parallel (because you then have a parallelogram).
Any polygon with four or more sides can have a pair of parallel sides. It is also possible to to have non-polygonal shapes - eg a cigar-shape - that has parallel sides.

A parallelogram is an quadrilateral (a figure with four edges and four vertices) with two sets of parallel sides. A trapezoid, also known as a trapezium, is a shape with four sides with a pair of parallel sides.
A trapezoid is a four-sided figure (or "quadrilateral") with only one pair of parallel sides.
The name of the four-sided shape that has only one pair of parallel sides is known as a trapezoid. The other two sides are not parallel to each other. There are many other shapes with more than four sides that have one pair of parallel sides but these typically don't have special names. So assuming the question is only referring to four-sided figures, the answer is a trapezoid.
A four-sided shape is a quadrilateral. With only one pair of parallel sides, it would be called a trapezoid (UK trapezium).
A rhombus is a shape with one pair of parallel sides. I has four sides and angles.
Any shape with four straight sides is a quadrilateral. A trapezoid has one pair of parallel sides, and a parallelogram has two pairs of parallel sides. So any shape with four straight sides and no parallel sides is a quadrilateral that is not a parallelogram or trapezoid.
