To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) A file group is a collection of physically distinct files that appear to the end user as multiple logical entities.
This option is incorrect because file groups are meant to appear as a single logical entity to the end user, not multiple logical entities.
Option B) A file group is a collection of logically distinct files that appear to the end user as a single logical entity.
This option is incorrect because file groups are not based on logical distinctions of files. They are based on physical distinctions.
Option C) A file group is a collection of physically distinct files that appear to the end user as a single logical entity.
This option is correct because file groups are indeed collections of physically distinct files that are presented to the end user as a single logical entity. This allows the user to interact with the file group as if it were a single file.
Option D) A file group is a collection of logically distinct files that appear to the end user as multiple logical entities.
This option is incorrect because file groups are not meant to appear as multiple logical entities. They are meant to appear as a single logical entity.
Therefore, the correct answer is C. A file group is a collection of physically distinct files that appear to the end user as a single logical entity.
