Mrs. Baker selects the 10 students whose names are drawn from a bag to fill out a survey. Option A is correct.

What is a random sample?

In statistics, a simple random sample is a subset of people chosen at random from a larger group, all of whom were chosen with the same probability. It is a method of choosing a sample at random.

In option A given that Mrs. Baker selects the 10 students whose names are drawn from a bag to fill out a survey. Here the students are selected randomly without any specific data Like age marks or birth date etc. It means that she is selecting the students randomly.

In all other options, the students are selected for their specific reasons like the 10 students who arrived at class first on Monday to fill out a survey or the 10 students with the highest grade point averages to fill out a survey, and the 10 students who raised their hands to volunteer to fill out a survey.

Hence, the correct option is A.
