with the given informtion there is a possibility that we can also get
Angle A = 90
Angle B =90
Angle C =45
Angle D = 155
so definite answer about the angles cannot be reached (since u can also get 90, 90, 60, 120)....so go with E

I think the ans shld be A
bcos if 2 side of quad are 90 each. the other 2 side shld also be 90 each. otherwise we cant form a quadilateral
pls correct me if I am wrong

refer the below link, the image on the bottom left helps you visualize that quadrilateral with two 90 degree angles and other two angles of different measure.

Hope this helps.

The correct answer is (E).
First, the sum of the internal angles of a quadrilateral is always 360º (can be decomposed in 2 triangles of 180º each)
A) is insufficient
we can have:
A=90
B=90
C=60
D=120
or
A=90
B=90
C=90
D=90
B) is insufficient
we can have
A=135
B=45
C=90
D=90
or
A=100
B=60
C=120
D=80
And together is also insufficient:
we can have
A=135
B=45
C=90
D=90
or
A=90
B=60
C=120
D=90
