Explanation:

Statements: J = O ≤ P, T > P > X, Y ≤ X = W, S > Y > R
Conclusions: T > S, J < Y, W > R
For conclusion I: T > S
From statements I, II and III, we get:
T > P > X ≥ Y < S
Here, we can see the opposite sign between T and S, thus no relationship can be established
between them.
Hence conclusion I does not follow.
For conclusion II: J < Y

From statements I, II and III, we get:
J = O ≤ P > X ≥ Y
Here, we can see the opposite sign between J and Y, thus no relationship can be established
between them.
Hence conclusion II does not follow.
For conclusion III: W > R
From statements III and IV, we get:
W = X ≥ Y > R
Here we can see that the common sign between W and R is '>'. Hence W > R.
Thus conclusion III follows.
Therefore only conclusion III follows.
Hence option C is correct.
