To ensure that no student scored below the mean on the examination given to 30 students, the correct answer would be: Option C: All 30 students had grades of C or better. Explanation: 1. The mean represents the average score of all the students. If no student scored below the mean, it means that all students performed at or above the average score. 2. By having all 30 students with grades of C or better, it ensures that none of the students falls below the mean score. 3. Even if some students scored exactly at the mean, as long as no student scored below it, the condition is met. Therefore, option C is the correct choice as it describes a scenario where all students had grades of C or better, leading to no student scoring below the mean on the examination.
