To create a random sample that accurately represents the population of 5th-grade students who like to play basketball, Carl should aim to ensure that his sample is unbiased and reflects the diversity of all 5th-grade students.
The best option would be:
**B. Carl should ask 30 5th-grade students.**
This option ensures that he is sampling directly from the population of interest (5th-grade students), rather than limiting his sample to those engaged in a specific activity (like basketball or football) or those from a specific school without ensuring they are representative of all 5th graders.
