In the given question, the word "GAMBLE" is coded as "FBLCKF". We need to find the coding for the word "FLOWER".

Let`s analyze the given coding pattern:

- Each letter in the original word is replaced by the letter which comes immediately before it in the English alphabet.

- For example, `G` becomes `F`, `A` becomes `Z`, `M` becomes `L`, `B` becomes `A`, `L` becomes `K`, and `E` becomes `D`.

Now, applying this pattern to the word "FLOWER":

- `F` becomes `E`, `L` becomes `K`, `O` becomes `N`, `W` becomes `V`, `E` becomes `D`, and `R` becomes `Q`.

- Therefore, the coded word for "FLOWER" is "EKNVDQ".

Now, let`s check the options:

- Option 1: GMPVDS - This option does not match the coding pattern.

- Option 2: GKPVFQ - This option does not match the coding pattern.

- Option 3: EMNXDS - This option matches the coding pattern. The correct answer is option 3.
