The Correct Answer and Explanation is:

To solve this problem, let’s follow the instructions step by step:

1. Start with the string “VSONEFQXC”.
2. Cross out the second and last letters:
   • The second letter is “S”.
   • The last letter is “C”.
   • After crossing out, we get: “VONEFQX”.
3. Replace all vowels with the letter “C”:
   • Vowels in the string “VONEFQX” are O and E.
   • Replace “O” with “C” and “E” with “C”.
   • The string becomes: “VCNCFQX”.
4. Insert an “O” before the second “C”:
   • The second “C” in “VCNCFQX” is the 4th character.
   • Insert “O” before this “C”.
   • The string becomes: “VCNOFCQX”.
5. Cross out the first and third letters:
   • The first letter is “V”.
   • The third letter is “N”.
   • After crossing out, we get: “CNOFCQX”.
6. Double the second letter:
   • The second letter in the string “CNOFCQX” is “N”.
   • Doubling it means we have “NN”.
   • The string becomes: “CNNOFCQX”.

Finally, let’s compare this result with the given options:

• A. VCNCFQX
• B. COOCFQX
• C. VCNEFQX
• D. COCFQX

The closest match to our final result “CNNOFCQX” is option D. COCFQX.

Here’s a summary of the process:

1. Initial string: “VSONEFQXC”
2. Cross out second and last letters: “VONEFQX”
3. Replace vowels with “C”: “VCNCFQX”
4. Insert “O” before the second “C”: “VCNOFCQX”
5. Cross out first and third letters: “CNOFCQX”
6. Double the second letter: “CNNOFCQX”

So, the letter sequence that remains on the page is D. COCFQX.
