Random allocation of subjects involves assigning participants to groups in a way that completely randomizes their assignment. Option A involves participants choosing the group they want to be in, which is not random. Option B involves systematic assignment of rats to groups based on the order they were pulled from the cage, which is not random either. Option D involves grouping participants based on a non-scientific factor, which is also not random. Option C, on the other hand, involves assigning numbers non-systematically and using a random number table to allocate participants to groups which ensures random allocation.
