Answer: D) At the next school assembly, choose one student from each of 20 randomly selected rows.

Step-by-step explanation:

A wouldnt be correct because it is all students from the spots program

B isnt correct because it is 10 girls and 10 boys from the girls' and boys' soccer teams

C wouldnt be correct because it would be the first 20 students she sees once she leaves statistics class

D is the only unbiased, completely random selection choice.
