The correct option is 2.
Step-by-step explanation:
From the given figure it is clear that the lines DEâ•‘RK, in triangle ODE and triangle OKR,
            (Vertical opposite angles)
            (Alternate interior angles)
            (Alternate interior angles)
By using AA property of similarity,
D is correspondence to K, O is correspondence to O, E is correspondence to R.
O ↔ O
Therefore the correct option is 2.
