A parallelogram has opposite sides parallel to each other.

Statement 1: All angles are 90 so that means that the quadrilateral is either a square or a rectangle and both have parallel sides equal. Hence A is sufficient.


Statement 2: All sides are equal which means that the qudrilateral is a square, rhombus or a parallelogram and since all of them have two pairs of parallel verteces, they are all parallelograms. Hence B is sufficient.

'D' is the correct answer.
