O
H
I
S
H
Identify vowels and consonants first, then perform the shift (+1 for consonants, -1 for vowels) and count the frequency of each resulting letter.
Identify vowels and consonants first, then perform the shift (+1 for consonants, -1 for vowels) and count the frequency of each resulting letter.
Mapping the letters
Original word: R H Y M I N G. Rules: Vowel - 1, Consonant + 1. Mapping: R(C)+1=S, H(C)+1=I, Y(C)+1=Z, M(C)+1=N, I(V)-1=H, N(C)+1=O, G(C)+1=H.
Analyze the result
The transformed letters are S, I, Z, N, H, O, H. The resulting sequence is S-I-Z-N-H-O-H.
Identify repeating letters
In the set (S, I, Z, N, H, O, H), the letter H appears twice (at positions 5 and 7). No other letter repeats.
A: Wrong frequency count, C: 'I' does not repeat, D: 'N' does not repeat.
B is correct because the letter H appears twice in the transformed sequence S-I-Z-N-H-O-H.
In transformation questions, always list the transformed sequence clearly to avoid missing duplicate letters hidden at the end or start of the string.
