In a certain code language, ‘SILK’ is written as ‘TIML’ and ‘INSECT’ is…

To determine the code for "CHANGE," we must first decode the pattern applied to "SILK" and "INSECT."

Decoding the Pattern
By analyzing the transformations, we can observe a consistent rule based on the type of letter:

Vowels (A, E, I, O, U): These letters remain unchanged (shift of +0).

Consonants: These letters are shifted to the next letter in the alphabet (shift of +1).

Verification:

SILK: S(C+1=T), I(V+0=I), L(C+1=M), K(C+1=L) → TIML (Matches)

INSECT: I(V+0=I), N(C+1=O), S(C+1=T), E(V+0=E), C(C+1=D), T(C+1=U) → IOTEDU (Matches)

Applying the Pattern to "CHANGE"
Following the same rule (Vowels +0, Consonants +1):

C (Consonant) + 1 = D

H (Consonant) + 1 = I

A (Vowel) + 0 = A

N (Consonant) + 1 = O

G (Consonant) + 1 = H

E (Vowel) + 0 = E

The resulting code is DIAOHE.
