Answer question based on following information :

Six products $\text{U, V, W, X, Y}$ and $\text{Z}$ are to be placed in display windows of a shop. There are six display windows numbered $1,2,3,4,5$ and $6$ and one product is to be put in one window. Moreover $\text{U}$ cannot be immediately to the left or immediately to the right of $\text{V, W}$ must be immediately to the left of $\text{X, Z}$ cannot be in window number $6 .$

If $\text{U}$ is placed in window no. $5$, which of the following products must be placed in window no. $6?$

1. $\text{W}$
2. $\text{V}$
3. $\text{X}$
4. $\text{Y}$

from the given information If $U$ is placed in window number $5$ then in window number, $6$ $Y$ is there because :

• $W, X$ cannot be there because X is on 3 and W is on 2.
• $U$ can not be immediately left or right of $V$ so if U is 5 then V can not be 6.

Option (D) is correct.
