A Correct answer
Explanation

Filters restrict result sets by applying conditions that narrow the data returned. Option B ('Filter occurrences') is vague and not a standard database concept. Option C is incorrect because while filters can reduce data volume, their primary purpose is data restriction, not performance enhancement - that's a side effect, not the function itself.
