A quadrilater with 1 right angle,1 obtuse angles,and 2 acute angles. AM i correct to say that prallelogram is the answer.

Nope
All I need is one counterexample.
I just drew a quadrilateral ABCD with C=90
A=85
B=120 and D=65
If it were a parallelogram then a pair of adjacent angles would have to add to 180
