To determine which set is a subset of set \( V \), we first look at the digits used in each set. Set \( V \) consists of the unique three-digit numbers formed using the digits \( 1, 2, 3, 4, \) and \( 5 \). Set \( W \) uses the digits \( 1, 3, \) and \( 5 \), which are all contained within set \( V \), making it a valid subset. Sets \( X, Y, \) and \( Z \) use digits that include \( 6, 0, \) and \( 7 \) respectively, which are not in set \( V \). Therefore, they cannot be subsets. Thus, the only set that is a subset of set \( V \) is set \( W \).
