Answer
Answer:
Roll a fair number cube. Use the number rolled to pick a row of students. Survey every student in that row.
Brief Explanations:
In cluster - sampling, the population is divided into clusters (here rows are clusters), and all elements in a randomly - selected cluster are sampled. In the first option, a row (a cluster) is randomly selected using a number cube, and all students in that row are surveyed, which is cluster sampling. The second option is stratified sampling based on grades. The third option is not cluster sampling as it divides by gender within rows. The fourth option is simple random sampling.
