(Left) ION APT ILK ASH (Right) In each of the words, each vowel is changed to the letter immediately following it in the English alphabetical order and each consonant is changed to the letter immediately preceding it in the English alphabetical order. In how many letter-clusters thus formed, will no vowel appear?

Identify words where all letters become consonants after transformation; since vowels always turn into the next letter, ensure no vowels (A, E, I, O, U) are generated in the result.

Define Transformation Rules
Rule 1: Vowel (A, E, I, O, U) тЖТ Next letter (+1). Rule 2: Consonant тЖТ Previous letter (-1).
Transform Each Word
Word 1 ION: I(V)+1=J, O(V)+1=P, N(C)-1=M. Result: JPM (No vowels). Word 2 APT: A(V)+1=B, P(C)-1=O, T(C)-1=S. Result: BOS (Contains vowel O). Word 3 ILK: I(V)+1=J, L(C)-1=K, K(C)-1=J. Result: JKJ (No vowels). Word 4 ASH: A(V)+1=B, S(C)-1=R, H(C)-1=G. Result: BRG (No vowels).
Final Count Verification
Resulting clusters: JPM, BOS, JKJ, BRG. Clusters without any vowels: JPM, JKJ, BRG. Total count = 3.
B: One is incorrect as it fails to count the three valid clusters. C: Two is incorrect as it misses one valid cluster. D: Four is incorrect as the word APT contains a vowel after transformation.
A is correct because the transformed clusters JPM, JKJ, and BRG contain no vowels, totaling three.
In transformation questions, always check the vowels first; if a vowel becomes a consonant (like I тЖТ J or A тЖТ B), keep track of the remaining characters carefully.
