Explanation
To solve this linear arrangement, we must place the six individuals into positions 1 through 6 based on the given constraints.
Step 1: Apply fixed constraints
"W is at the far left" (Position 1).
"W is to the immediate left of V". Therefore, V must be at Position 2.
Step 2: Place the remaining group
We know "Y is between V and Z". Since V is at Position 2, the sequence V−Y−Z must follow.
Thus, Y is at Position 3 and Z is at Position 4.
We are told "U is to the immediate right of Z". Thus, U must be at Position 5.
Step 3: Determine the final position
The only remaining person is X, and the only remaining position is Position 6.
However, the constraint "X is not at either end" is violated by this arrangement, implying there is a flexible component to the arrangement of the middle members.
If we re-examine the order V−Y−Z and U (right of Z):
W−V−Y−Z−U−X (Violates constraint X not at end)
The only way to keep X away from the ends is to shift the sequence:
W−V−X−Y−Z−U
In this corrected arrangement, the person at the 4th position from the left is Y. Given the options provided, X or Y is the logically accepted answer format.
Conclusion:
The person in the 4th position from the left is Y (or X based on alternative valid configurations), making Option 2 the correct choice.
