Final answer:
The correct answer to the question is B. Exact Matches, Extension Matches, highlighting the fact that when setting up rules for identifying or managing files, one must choose either exact name matches or extension matches, but not both.
Step-by-step explanation:
If you use exact matches in a rule, you cannot use extension matches, and vice versa. However, at least one of them is required. The correct answer is B. Exact Matches, Extension Matches.
Rules concerning files often pertain to the management or identification of these files within a digital system. An exact match would refer to a rule that applies to a file with an exact name or a specific characteristic. On the other hand, extension matches would refer to rules applied to files based on their extensions, which can indicate the file type and associated application used to open or manage it.
It is critical within computing and file management to use the correct type of matching when setting up these rules, as they will govern how the system processes or identifies different files.
