Final answer:
The correct answer is C. Metadata Files, which indicates the find and replace operation will be applied to each file with a name listed in the metadata files, not to file names, file extensions, or requiring exact content matches.
Step-by-step explanation:
The correct answer to the question is C. Metadata Files. This refers to metadata files which are files that contain data about other data, in contrast to the actual content. In the context of find and replace operations, metadata files may include configurations or settings that specify how the find and replace function should behave. The rule mentioned in the question suggests that the operation will be performed on files with names exactly matching those on a list. This is not a search for file names based on their titles alone nor is it a replacement within the data based solely on file extensions or patterns requiring exact matches within the content of the files.
