What term describes an expression that evaluates to true or false?

• A. Distinct
• B. All
• C. Boolean Expression
• D. Date

Answer: (C)

Boolean expressions describe conditions that can be true or false. They’re built from comparisons and logical operators, and they’re what you test in a WHERE clause or in CASE statements. This makes them the term that describes an expression which evaluates to true or false. Distinct is a keyword used to remove duplicates from results, not a type of expression. All is a quantifier or keyword that can mean every row or value in a comparison, not the kind of expression that yields a boolean result on its own. Date is a data type for calendar dates, not a condition. Examples of boolean expressions include a > 5, status = 'active', or age >= 18 AND country = 'US'.
