It's A. All 10th grade students is focusing on one particular group, as well is the 1st lunch period compared to the other 3, and all students who bring their own lunch would be a terrible choice for asking them about buying food.

I think you're right though. Option "A" makes the most sense. It's the most random and the most inclusive of all the students.
