Directions: Study the following questions carefully and choose the...

In order to ensure the statement that holds ' W > Z' and ' Y > Z' definitely true, we have to check all the options one by one.

For option A:

W > X > U = Z < H& ≤ Y

Here, the common sign between W and Z is '>', thus it& follows& W > Z.

The common sign between Z and Y is also '<' , thus it& follows& Z < Y or Y > Z.

For option B:

W& ≥ X = U > Z& ≤ H < Y

Here also, the common sign between W and Z is '>', thus it& follows& W > Z.

The common sign between Z and Y is also '<' , thus it& follows& Z < Y or Y > Z.

For option C:&

W = X > U ≥ Z < H < Y

Here again, the common sign between W and Z is '>', thus it& follows& W > Z.

The common sign between Z and Y is also '<' , thus it& follows& Z < Y or Y > Z.

Since all the three expressions hold the given conclusions true, option D "all of the above" is correct.

Hence option D is correct.
