The proper way to refer to Chlamydomonas reinhardtii after the full binomial has been used once is to use the genus abbreviation "C." followed by the species name "reinhardtii", as in option D. This abbreviated form is widely used in scientific literature to save space and avoid repetition. It is also clear and unambiguous, as there is only one species within the genus Chlamydomonas that has this specific species name. Options A, B, and E are incorrect, as they either repeat the full binomial name or use an incorrect or non-existent species abbreviation. Option C is also incorrect, as using "sp." as a designation would indicate uncertainty about the species identity.
