The redox centers should be ranked in order of increasing ability to produce a favorable electron flow. This means that the centers with less of an affinity for electrons should be listed before those with a greater affinity. Looking at the table, we can see that Q has the lowest reduction potential (-0.68 V) and therefore the least affinity for electrons. Therefore, it should be ranked first. F has the next lowest reduction potential (-0.45 V), followed by C (-0.28 V), D (0.07 V), and Z (0.80 V). So the correct order is Q, F, C, D, and Z. Therefore, option B is the best choice.
