E). taking a poll in the lunch room (where all students currently have to eat lunch) to determine the number of students who want to be able to leave campus during lunch

It seems that when gathering a sample, it should nearly be able to grasp the entire population. Sample represents the population being studied. In this case, the poll can subject all the participants since they all are utilizing the area. In addition, this lets them have an equal chance of participating with a high degree of representing the population.
