The answer is B. Shape A is a square which all the sides are the same length. This mean it has 2 pairs of parallel sides. Shape B is a rectangle which also has 2 pairs of parallel sides. Shape C is rhombus which also has 2 pairs of parallel sides. Shape D is a trapezoid which only has 1 pair of parallel sides.
the second one is correct. the first one is wrong because shape C also has those angles. the third one is wrong because shape C also has no perpendicular sides. the fourth one is wrong because shape C also has 2 pairs of angles with the same measure.
