It might be the coolest PE class ever. The Chongqing branch of Southwest University of Political Science & Law is offering a motorcycle class to all its students. Every semester, more than 600 students apply for the 150 spots available in the class. The class used to be a compulsory class for students majoring in criminal investigation, but is now an optional course open to all students. However, passing the course doesn't automatically mean you can ride on the roads – you still need to obtain a license, of course!

How many students can attend the class at the same time?

A. 150

B. 600

C. All in the school
