In randomized controlled experiments, it is important to randomly assign participants to the experimental and control groups to avoid any bias and ensure that the groups are equivalent at the beginning of the experiment. This randomization can be done using software, a table of random numbers, or some other random process. The participants themselves or the experimenters should not be the ones choosing the group assignments to avoid potential bias. Therefore, the correct answer is C, a random process.
