Detailed Solution & Explanation

To find the code for the word **MOTEL** based on the codes **CLOCK** =34235\displaystyle = 34235 and **TIME** =8679\displaystyle = 8679, let us extract the direct letter-to-digit mappings:

From **CLOCK** =34235\displaystyle = 34235:
- C→3\displaystyle C \to 3
- L→4\displaystyle L \to 4
- O→2\displaystyle O \to 2
- K→5\displaystyle K \to 5

From **TIME** =8679\displaystyle = 8679:
- T→8\displaystyle T \to 8
- I→6\displaystyle I \to 6
- M→7\displaystyle M \to 7
- E→9\displaystyle E \to 9

Now, we apply these mappings to the word **MOTEL**:
- M→7\displaystyle M \to 7
- O→2\displaystyle O \to 2
- T→8\displaystyle T \to 8
- E→9\displaystyle E \to 9
- L→4\displaystyle L \to 4

Putting the digits together in sequence, the code for **MOTEL** is **72894**.

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