A Correct answer
Explanation

SQL allows multiple CHECK constraints on a single column because each constraint is evaluated independently. For example, you could have one CHECK ensuring age >= 18 and another ensuring age <= 65 on the same column. All CHECK constraints must be satisfied for any INSERT or UPDATE operation on that column.
