John states that all trapezoids have at least one line of symmetry. What reasoning proves or disproves John's claim?

A
John's claim is true because all trapezoids have a line of symmetry through their parallel bases.
B
John's claim is false because only isosceles trapezoids have a line of symmetry through their parallel bases.
C
John's claim is true because trapezoids have one line of symmetry and isosceles trapezoids have two lines of symmetry.
D
John's claim is false because all trapezoids have a line of symmetry through their parallel bases and through the other two sides.
