Explanation:

To find the code for 'FRESH' we must understand the pattern used to encode 'DOUGH' as 'WLFTS'.

- Look at the mapping between each character in 'DOUGH' and 'WLFTS':

- D -> W

- O -> L

- U -> F

- G -> T

- H -> S

- Each letter in 'DOUGH' is replaced by a letter that is obtained by subtracting 5 positions in the alphabet (e.g., 'O' to 'L', 'U' to 'F').

- Let's apply the same pattern to encode 'FRESH':

- F (6th letter) becomes U (21st letter)

- R (18th letter) becomes I (9th letter)

- E (5th letter) becomes V (22nd letter)

- S (19th letter) becomes H (8th letter)

- H (8th letter) becomes S (7th letter)

Correct Coding: 'FRESH' is written as 'UIVHS'.

- Option:1 – VKFHS

Incorrect: Doesn't follow the -5 logic for all letters.

- Option:2 – UKERT

Incorrect: Random letter changes, not following the pattern.

- Option:3 – WKGSS

Incorrect: Wrong transformation.

- Option:4 – UIVHS

Correct: Follows the -5 position shift rule accurately.
