Explanation:

- To find the pattern in coding, look at letter shifts in WIDOWER to VKAOXCU:

- W to V (-1)

- I to K (+2)

- D to A (-3)

- O to O (0)

- W to X (+1)

- E to C (-2)

- R to U (+3)

- Check if this pattern applies when coding FORTIFY.

- F applying -1 = E

- O applying +2 = Q

- R applying -3 = O

- T applying 0 = T

- I applying +1 = J

- F applying -2 = D

- Y applying +3 = B

- FORTIFY coded becomes EQOTJDB.

- Option:1 - EQOTJDB matches the pattern.
