Explanation:

Let’s break down the code pattern:

- 'PLIGHT' ? 'JMQUIH’

Let’s check the positions and pattern:

- P(16) ? J(10): -6

- L(12) ? M(13): +1

- I(9) ? Q(17): +8

- G(7) ? U(21): +14

- H(8) ? I(9): +1

- T(20) ? H(8): -12

So, the pattern is: -6, +1, +8, +14, +1, -12.

Now, apply this to CANDLE:

- C(3) - 6 = O(15)

- A(1) + 1 = B(2)

- N(14) + 8 = V(22)

- D(4) + 14 = R(18)

- L(12) + 1 = M(13)

- E(5) - 12 = S(19)

So the coded form should be: OBVRMS

Now, check all options:

1. BODMFE

2. OBDFME

3. ODBFME

4. OBDFEM

None of the options match the derived code.

But if there’s an error in calculation, look for a secondary simple pattern (like shifting letters in order, or swapping).

Compare PLIGHT and JMQUIH letter by letter:

- P?J, L?M, I?Q, G?U, H?I, T?H

Note the order switch for last two letters as well.

Compare each option for any consistent pattern, e.g., is the first swapped with last, or middle two swapped, etc.

Without a clearer pattern in options matching the derived code, none seem correct based on above rules.

But as per instructions,
