The angle between L2 and L3 is equal to 50. Corresponding angles.

And x+x+50 = 180.
2x = 130.
x = 65.

D is the answer

On the line l3, x+x+unknown angle=180
Or, 2x+unknown angle=180

L1 || L2, so, alternate angles are equal, hence, unknown angle=50.

So, 2x+50=180
Or, 2x=130
or, x=65

Ans. (D)

$$2x = 130$$ ( Supplementary angle of 50 degree and Corresponding angle of parallel lines )

So, $$x = 65$$ , Answer must be (D)
