The correct option is C OYPTD
Given, VOYAGE is coded as FIBAPX.
Here, the order of letter 'VOYAGE' is reversed to obtain new word 'EGAYOV'. Now,
E +1−−−→ F
G +2−−−→ I
A +1−−−→ B
Y +2−−−→ A
O +1−−−→ P
V +2−−−→ X
Similarly, the letter of word CROWN is first reversed to obtain the word NWORC. Now,
N +1−−−→ O
W +2−−−→ Y
O +1−−−→ P
R +2−−−→ T
C +1−−−→ D
So, CROWN is coded as OYPTD.
Hence, option (C) is the correct answer.
