In a certain code language, ‘SILK’ is written as

Solution

Logic:  Add 1 to the place value of each letter of the given words and the vowels in the given words will remain the same. Explanation:  ‘SILK’ to ‘TIML’: S + 1 = T 'I' is a vowel. It will remain the same. L + 1 = M K + 1 = L And, ‘INSECT’ to ‘IOTEDU’: 'I' is a vowel. It will remain the same. N + 1 = O S + 1 = T 'E' is a vowel. It will remain the same. C + 1 = D T + 1 = U Now, let’s apply the same pattern to ‘CHANGE’: C + 1 =  D H + 1 =  I ' A ' is a vowel. It will remain the same. N + 1 =  O G + 1 =  H ' E ' is a vowel. It will remain the same. So, 'CHANGE' is written as ' DIAOHE '. Therefore, the correct option is (d).
