Best answer

Correct option is (C) ∠DOC

Since, equal chord subtends equal angles at the centre of the circle.

Also, \(\angle AOB=\) Angle subtend by chord AB at the centre of the circle (O).

\(\angle DOC\) = Angle subtend by chord CD at the centre of the circle (O).

and AB = CD

\(\therefore\) \(\angle AOB=\) \(\angle DOC\)
