To determine which set is a subset of set $$ V $$, let's analyze each option based on the digits they use:

- **Set $$ V $$**: Contains all unique three-digit numbers using the digits **1, 2, 3, 4,** and **5**.

- **Set $$ W $$**: Uses the digits **1, 3,** and **5**.
  - **All digits (1, 3, 5) are in set $$ V $$.** 
  - Therefore, **$$ W $$ is a subset of $$ V $$**.

- **Set $$ X $$**: Uses the digits **2, 4,** and **6**.
  - **Digit 6 is not in set $$ V $$.**
  - Therefore, **$$ X $$ is not a subset of $$ V $$**.

- **Set $$ Y $$**: Uses the digits **0, 2,** and **4**.
  - **Digit 0 is not in set $$ V $$** (since $$ V $$ only includes digits 1 through 5).
  - Therefore, **$$ Y $$ is not a subset of $$ V $$**.

- **Set $$ Z $$**: Uses the digits **3, 5,** and **7**.
  - **Digit 7 is not in set $$ V $$**.
  - Therefore, **$$ Z $$ is not a subset of $$ V $$**.

**Conclusion:** Only **Set $$ W $$** is a subset of set $$ V $$.

**Answer:** Set $$ W $$ is a subset of set $$ V $$.
Set $$ W $$ is a subset of set $$ V $$.
