9. Copy the letter string above on a piece of paper. Cross out the second and last letters. Replace all vowels with the letter C. Insert an O before the second C. Cross out the first and third letters. Double the second letter. Which of the following letter sequences remains on the page?
Answer: B
B
Following the given instructions systematically leads to the letter sequence CFFMMC. Each transformation aligns precisely with the steps provided in the question.
A) SFFMOC
This option is incorrect because the transformations do not yield this sequence. The initial letter string does not lead to SFFMOC after applying the steps of crossing out letters and replacing vowels.
B) CFFMMC
This option is correct as it accurately reflects the final letter sequence after executing all the specified operations. Each step has been followed correctly, resulting in CFFMMC being the final output.
C) SSFMOI
This choice is incorrect because it introduces additional letters and changes that do not match the transformations outlined in the question. The presence of an 'I' at the end is particularly erroneous, as it contradicts the instructions regarding vowel replacement.
D) FSCFMS
This option is also incorrect. The transformations do not lead to FSCFMS, as it fails to account for the correct vowel substitutions and letter crossings specified in the task.
Conclusion
CFFMMC is the only sequence that accurately follows the provided instructions. All other options either misrepresent the transformations or introduce incorrect characters, underscoring the importance of following each step methodically to arrive at the correct answer.
