Step 1: Analyzing the views.
Views X and Y show the object from different angles. By looking at the signs on the object, we can deduce the missing sign from View Z by matching the shape and pattern from the two previous views.
Step 2: Identifying the missing sign.
Based on the signs in Views X and Y, the missing sign in View Z is best represented by option (C).
\[
\boxed{(C)}
