Explanation:

- The given code language involves analyzing the transformation of each letter.

- For 'WORLD' to 'CUXRJ':

- W(23) to C(3) -> +6

- O(15) to U(21) -> +6

- R(18) to X(24) -> +6

- L(12) to R(18) -> +6

- D(4) to J(10) -> +6

- For 'SMOKE' to 'YSUQK':

- S(19) to Y(25) -> +6

- M(13) to S(19) -> +6

- O(15) to U(21) -> +6

- K(11) to Q(17) -> +6

- E(5) to K(11) -> +6

- Applying the same pattern to 'INDIA':

- I(9) + 6 = O(15)

- N(14) + 6 = T(20)

- D(4) + 6 = J(10)

- I(9) + 6 = O(15)

- A(1) + 6 = G(7)

- Therefore, 'INDIA' becomes 'OTJOG' in the code.

Correct Answer: Option 3 - OTJOG
