b. Randomly selecting a sample to participate in the experiment.
This is the correct answer because random assignment refers to the process of assigning participants to different groups in an experiment in a random manner. In this case, Carson needs to randomly select a sample of mice to participate in the experiment in order to ensure that the results are not biased and that any differences observed can be attributed to the muscle growth formula being tested. Random assignment helps to eliminate potential confounding variables and strengthens the internal validity of the experiment.
