Acc. to the attached fig.
AOD=180-95=85°
AXD=85/2=42.5°( As X is on the circumference , AXD will be half the Angle at the centre)
AXO=XAO( both are radi, therefore they are equal, hence form an isosceles triangle)
AXO=XAO=42.5°.............(i)

BOD=95°
BXD=95/2=47.5°
BXO=XBO(------DO------)
BXO=XBO=47.5°..........(ii)

ACB=90°(  angle subtended by the diameter)
ABC=90-x....(iii)

Now, AXBC forms a cyclic quad.
So, A+B=180
x+42.5=47.5+90-x
2x=95
x=42.5

So, the crrt option wud be E) None.

AOD=85 so AXD=85/2

given :-
bod = 95  ,
o is center  and
ab is diameter

solution :-

BOD=95°
BXD=95/2=47.5°
BXO=XBO(------DO------)
BXO=XBO=47.5°    -1

ACB=90 °(  angle subtended by the diameter)
ABC=90-x.         -2

AOD=180-95=85°
AXD=85/2=42.5°( As X is on the circumference , AXD will be half the Angle at the centre)
AXO=XAO( both are radi, therefore they are equal, hence form an isosceles triangle)
AXO=XAO=42.5°    -3

Now, AXBC forms a cyclic quad.
So, A+B=180
x+42.5=47.5+90-x
2x=95
x=42.5

hence option e is the answer
