Answer:
D. Supervisor ranking of subordinates from highest performing to lowest performing
Step-by-step explanation:
Comparative system as a performance rating system is the analysis of a number of subordinates in relation to their performance, key comparative indicator here is analyzing the level performance between all of the subordinates involved.
If it were to be an absolute system as a form of performance comparison, each subordinate would have been examined by the supervisor individually without facilitating a comparison with other subordinates. Comparative system is the opposite of the absolute system.
