Correct Answer

Two

Algorithmic Application: The rule dictates adding +1 to all vowels (A,E,I,O,U) and applying -1 to all consonants.Cluster 1 Transformation: For 'DIE': D(-1)=C, I......

💡 Analysis & Explanation

Algorithmic Application ▼

The rule dictates adding +1 to all vowels (A,E,I,O,U) and applying -1 to all consonants.

Cluster 1 Transformation ▼

For 'DIE': D(-1)=C, I(+1)=J, E(+1)=F. Result is 'CJF' (Contains 0 vowels).

Cluster 2 Transformation ▼

For 'CUP': C(-1)=B, U(+1)=V, P(-1)=O. Result is 'BVO' (Contains 1 vowel: O).

Cluster 3 Transformation ▼

For 'BOX': B(-1)=A, O(+1)=P, X(-1)=W. Result is 'APW' (Contains 1 vowel: A).

Cluster 4 Transformation ▼

For 'ASK': A(+1)=B, S(-1)=R, K(-1)=J. Result is 'BRJ' (Contains 0 vowels).

Conclusion ▼

Tallying the processed strings, exactly two new clusters ('CJF' and 'BRJ') completely lack vowel representation.
