A professor will cancel his sociology class if the number of students in attendance is less than or equal to 10. Which of the following expressions would give the possible values of students, S, necessary for the professor to conduct class, given that S is an integer?

• A. S < 10
• B. S > 10
• C. S ≤ 10
• D. S ≥ 10

Correct Answer: B
