Analyze the code FISH → GJTJ by comparing each letter's alphabetical position:
F → G:
- F = 6, G = 7 → Shift: +1
I → J:
- I = 9, J = 10 → Shift: +1
S → T:
- S = 19, T = 20 → Shift: +1
H → J:
- H = 8, J = 10 → Shift: +2
So the pattern is: First three letters are shifted by +1, and the last letter is shifted by +2.
Now apply this pattern to the word BIRD:
B = 2 → B +1 = 3 → C
I = 9 → I +1 = 10 → J
R = 18 → R +1 = 19 → S
D = 4 → D +2 = 6 → F
Thus, BIRD becomes: CJSF
Check the options:
(A) CJSE (B) CJTD (C) DJSE (D) CJTE
None match exactly. Option (A) is very close, differing only in the last letter:
- D = 4 → E = 5 → Shift: +1
This suggests that the last letter might actually be shifted by +1 instead of +2 in this case.
So applying +1 to D:
- D = 4 → D +1 = 5 → E
Final coded form of BIRD: CJSE
Therefore, the answer is:
Answer: (A) CJSE
