Detailed Solution & Explanation

To find the code for the word **YES** based on the given codes **MOUSE** =34651\displaystyle = 34651 and **KEY** =217\displaystyle = 217, let us extract the direct letter-to-digit mappings:

From **MOUSE** =34651\displaystyle = 34651:
- M→3\displaystyle M \to 3
- O→4\displaystyle O \to 4
- U→6\displaystyle U \to 6
- S→5\displaystyle S \to 5
- E→1\displaystyle E \to 1

From **KEY** =217\displaystyle = 217:
- K→2\displaystyle K \to 2
- E→1\displaystyle E \to 1
- Y→7\displaystyle Y \to 7
*(We note that the mapping for E→1\displaystyle E \to 1 is perfectly consistent in both words).*

Now, we apply these mappings to the word **YES**:
- Y→7\displaystyle Y \to 7
- E→1\displaystyle E \to 1
- S→5\displaystyle S \to 5

Putting the digits together in sequence, the code for **YES** is **715**.

Hence, **Option A** is the correct answer.
