In a certain code language, 'NAME’ is written as 'FNBO' and 'NANO' is written…

Analyze 'NAME' → 'FNBO':

N (position 14) → F (position 6): This is a shift of -8.

A (position 1) → N (position 14): This is a shift of +13.

M (position 13) → B (position 2): This is a shift of -11.

E (position 5) → O (position 15): This is a shift of +10.

Wait, let's re-examine the pairing:

N → O (+1)

A → B (+1)

M → N (+1)

E → F (+1)

Notice the sequence: NAME becomes FNBO.

E + 1 = F

M + 1 = N

A + 1 = B

N + 1 = O

The word is reversed, and each letter is shifted by +1.

Verify with 'NANO' → 'POBO':

Reverse NANO: O, N, A, N.

Shift each by +1:

O + 1 = P

N + 1 = O

A + 1 = B

N + 1 = O

Result: POBO. The pattern is confirmed: Reverse the word, then shift each letter by +1.

Apply to 'NAIL':

Reverse NAIL: L, I, A, N.

Shift each by +1:

L + 1 = M

I + 1 = J

A + 1 = B

N + 1 = O

Result: MJBO.
