Identify vowels (A, E, I, O, U) first. If a word contains a vowel, the transformed word will contain a vowel only if the transformation doesn't turn a consonant into a vowel. Since Vowel тЖТ Vowel+1 and Consonant тЖТ Consonant-1, just check if the new set of letters contains A, E, I, O, or U.

Analyze GIR
G (Consonant: G-1=F), I (Vowel: I+1=J), R (Consonant: R-1=Q). Word becomes FJQ. Contains no vowels. (Count: 1)
Analyze PVT
P (Consonant: P-1=O), V (Consonant: V-1=U), T (Consonant: T-1=S). Word becomes OUS. Contains vowels O and U. (Count: 1)
Analyze DEC
D (Consonant: D-1=C), E (Vowel: E+1=F), C (Consonant: C-1=B). Word becomes CFB. Contains no vowels. (Count: 2)
Analyze NOW
N (Consonant: N-1=M), O (Vowel: O+1=P), W (Consonant: W-1=V). Word becomes MPV. Contains no vowels. (Count: 3)
A: One is incorrect as it misses the three valid clusters. B: Four is incorrect as only three clusters result in no vowels. C: Two is incorrect as it underestimates the count by one.
D is correct because the transformed words FJQ, CFB, and MPV contain no vowels, totaling three clusters.
When checking for vowels in transformed words, remember that the shift rule (Vowel+1, Consonant-1) is simple; focus only on identifying if A, E, I, O, U appear in the final output.
