Detailed Solution & Explanation

To find the code for the word **PILLER** based on the given codes **RIPPLE** =613382\displaystyle = 613382 and **LIFE** =8192\displaystyle = 8192, let us extract the direct letter-to-digit mappings:

From **RIPPLE** =613382\displaystyle = 613382:
- R→6\displaystyle R \to 6
- I→1\displaystyle I \to 1
- P→3\displaystyle P \to 3
- L→8\displaystyle L \to 8
- E→2\displaystyle E \to 2

From **LIFE** =8192\displaystyle = 8192:
- L→8\displaystyle L \to 8
- I→1\displaystyle I \to 1
- F→9\displaystyle F \to 9
- E→2\displaystyle E \to 2
*(We note that the mappings for L\displaystyle L, I\displaystyle I, and E\displaystyle E are perfectly consistent in both words).*

Now, we apply these mapped values to the word **PILLER**:
- P→3\displaystyle P \to 3
- I→1\displaystyle I \to 1
- L→8\displaystyle L \to 8
- L→8\displaystyle L \to 8
- E→2\displaystyle E \to 2
- R→6\displaystyle R \to 6

Putting these digits together in sequence, the code for **PILLER** is **318826**.

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