We start by identifying the operation and the input string. The formula REPLACE("Year2022", 5, 4, "2023") means: take the text "Year2022", begin at position 5, remove 4 characters, and insert the text "2023" in their place. In the string "Year2022", the character positions are: 1:Y, 2:e, 3:a, 4:r, 5:2, 6:0, 7:2, 8:2. Starting at position 5 and removing 4 characters, we remove the substring "2022" (positions 5–8). Replacing it with "2023" yields the new string "Year2023".

Option by option:
- Option "Year2054": This would imply substituting a different suffix, but the operation specifically replaces 4 characters starting at 5 with "2023"; there is no path that yields "Year2054" from the given inputs.
- Option "2023": This would be the result if only the inserted portion were returned, but REPLACE returns a full string, not just the inserted fragment.
- Option "Year20": This would occur if only two characters after position 5 were affected, which does not match replacing 4 characters starting at 5 with a 4-character string.
- Option "Year2023": This matches the actual outcome after performing the replacement described above, producing the full string with the new tail.

In summary, the replacement operation transforms "Year2022" into "Year2023" by substituting the last four characters (starting at position 5) with the new text "2023". The other options misinterpret the scope of the replacement or the resulting full string.
