Answer:
The correct option is 2.
Step-by-step 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://tex.z-dn.net/?f=%5Ctriangle%20DOE%5Csim%20%5Ctriangle%20KOR)
D is correspondence to K, O is correspondence to O, E is correspondence to R.
O ↔ O
Therefore the correct option is 2.
