Community Service is one of Ahmed’s passions. Ahmed wants to survey a random sample of the students in his school to find out which day after school would work best for students to do volunteer work for a local food bank. Which sample would best represent the students in his school?
A Surveying twenty students waiting in line for lunch
B Surveying twenty students on their way to the bus after school
C Surveying one person from the seventh grade daily for twenty days
D Surveying one person each from twenty different classrooms during the first class period
