I think answer should be E (30 deg). Request experts to please share solution.

My solution: Assume B as the center of a circle. And A, E and D lie on the circumference of this circle.
Now, angle subtended by chord DE at the center is 20 (angle EBD), and on the angle subtended at point A is 10 (angle EAD).
Simlarly, for chord AD: angle ABD = twice the angle AED => 60 = 2x
=> x = 30 (Answer)

Logic used: Angle subtended by the chord at the center is twice the angle subtended by it at any other point on the remaining part of the circle.
