Answer:

Correct option is

B

90

,90

,90

Let AB and CD be two lines Intersecting at O, such that, ∠AOD=90

Now, ∠AOD=∠COB=90

(Vertically opposite angles)

⟹∠AOD+∠DOB=180

o

(Angles on a straight line)

⟹90+∠DOB=180

o

∠DOB=90

∠DOB=∠AOC=90

(Vertically opposite angles)

Thus, all angles are 90
