Explanation:

Statements: D ≥ S , X < W, S = J, W > Y, X > D, Y ≤ O, J ≥ E
Conclusions: (i) D > E (ii) D = E (iii) O > S

By combining all the statements, we get the following equation:
O ≥ Y < W > X > D ≥ S = J ≥ E

For conclusion (i): D > E
Here, the common sign between D and E is '≥'. Thus D ≥ E.
Hence conclusion (i) does not follow individually.
For conclusion (ii): D = E

Here, the common sign between D and E is '≥'. Thus D ≥ E.
Thus conclusion (ii) does not follow individually.
On combining conclusions I and II we get "D ≥ E".
Therefore either conclusion (i) or (ii) follows.
For conclusion (iii): O > S
Here we can see the opposite signs between O and S, thus no relationship can be established between them.
Therefore conclusion (iii) does not follow.
