Hi,
Can someone please explain the answer A?
from both A & B each considered alone we can say that they can be rectangel, rhoumbus, IIogram or trapeizium. Hence INSUFFICIENT
Combining them also does not change the situation. HENCE INSUFFICIENT.
I would normally go for E and not A.
Cheers

well Option A says PS = QR and according to the question PS ll QR ... hence PQ has to be equal and parallel to RS ....since connecting two equal and ll lines. Otherwise the easiest way to find out whether it is a parallelogram or not draw two lines parallel and equal to each other and connect them with other two lines and see it will form a parallelogram Therefore, this option is sufficient Attachment:

Option B tells us that PQ = RS Now, it does not tell us anything about PS and QR ... they can be unequal ... hence this option is insufficient to answer Attachment:

Hence answer option A

Great question!
Definitely helps to draw these figures on a piece of paper and think logically about them.
A is of course correct as it satisfies the condition required of a parallelogram.
