If LSJXVC is the code for MUMBAI, the code for DELHI is

The correct option is CCIDD.

To find the code for DELHI, let us analyze the pattern used to decode the word MUMBAI into LSJXVC.

Let us write down the letters of the alphabet and their corresponding numerical positions (A = 1, B = 2, ..., Z = 26):

M = 13, U = 21, M = 13, B = 2, A = 1, I = 9
L = 12, S = 19, J = 10, X = 24, V = 22, C = 3

Now, let us compare each letter of the original word MUMBAI with the coded letter LSJXVC:

First letter: M (13) ⇒ L (12), which is 13 - 1 = 12 (subtract 1)
Second letter: U (21) ��� S (19), which is 21 - 2 = 19 (subtract 2)
Third letter: M (13) ⇒ J (10), which is 13 - 3 = 10 (subtract 3)
Fourth letter: B (2) ⇒ X (24). In a circular alphabet where A is preceded by Z (26), B (2) - 4 = -2, which corresponds to 26 - 2 = 24 (X) (subtract 4)
Fifth letter: A (1) ⇒ V (22). Similarly, A (1) - 5 = -4, which corresponds to 26 - 4 = 22 (V) (subtract 5)
Sixth letter: I (9) ⇒ C (3), which is 9 - 6 = 3 (subtract 6)

The pattern is to subtract consecutive integers: -1, -2, -3, -4, -5, -6, ... from the alphabetical position of each letter in the word.

Applying the same logic to the word DELHI:

D (4) - 1 = 3 ⇒ C
E (5) - 2 = 3 ⇒ C
L (12) - 3 = 9 ⇒ I
H (8) - 4 = 4 ⇒ D
I (9) - 5 = 4 ⇒ D

Putting the letters together, we get CCIDD.
