Explanation:

Let's analyze the coding method:

- EXAMPLE ? DWZLOKD

- E ? D (-1)

- X ? W (-1)

- A ? Z (-1)

- M ? L (-1)

- P ? O (-1)

- L ? K (-1)

- E ? D (-1)

- Every letter is replaced by its previous letter in the alphabet.

Now, let's code ELECTION using this pattern:

- E ? D

- L ? K

- E ? D

- C ? B

- T ? S

- I ? H

- O ? N

- N ? M

So, ELECTION ? DKDBSHNM

Let's check the options:

1. DKEBSHNM

2. EKDBSHNM

3. DKDBSHNM

4. DKDBSJHM

The correct answer is:

Option 3: DKDBSHNM

- Each letter is replaced with its previous letter.

- Only option 3 matches the pattern.
