Based on the information given, can you determine that the quadrilateral must be parallelogram? Explain.

A. Yes, because opposite sides in a parallelogram are congruent
B.Yes, because diagonals bisect each other in a parallelogram
C.Yes, because opposite sides in a parallelogram are parallel
D.No, this is not enough information

D. No, this is not enough information. Neither congruent sides nor diagonals bisecting each other imply that the quadrilateral is a parallelogram. Without any further information, we cannot make such a determination.
