D. Asking students to call a phone number to answer survey questions

Step-by-step explanation:

➷ A. choosing every 10th name on the student roster.

This is the most random as it is non biased. The first and second one are biased towards the student who arrive early and therefore, wouldn't produce a random sample. The last one is also not random as it relies on volunteers.
