Answer:
The correct option is 2.
Explanation:
From the given figure it is clear that the lines DE║RK, in triangle ODE and triangle OKR,
(Vertical opposite angles)
(Alternate interior angles)
(Alternate interior angles)
By using AA property of similarity,
![\triangle DOE\sim \triangle KOR](https://img.qammunity.org/2020/formulas/mathematics/middle-school/f363u529vc94av9aur7tbkeo45hgp7eek2.png)
D is correspondence to K, O is correspondence to O, E is correspondence to R.
O ↔ O
Therefore the correct option is 2.
