Answer:
All personnel decisions must be made on C. objective criteria.
Explanation:
Within any <em>company or organization</em>, all decisions regarding the personnel should be made under objective criteria so as to give every employee a fair stand.
Let's see why the other options are unjust:
- Subjective preferences: this means someone might be getting <em>favored or unfavored</em> in account of what the individual carrying out the decision, thus this is not a fair option.
- Sexual preferences: again, the person might get favored or unfavored based on a sexual preference which is unfair once again.
- National origin: it should not be taken into account when carrying out decisions for the personnel.
According to Gregory Mankiw, a US teacher and economist, this example would demonstrate the economic principle of "the significance of opportunity cost in decision making". Martina had to give up going to restaurants in order to continue travelling by taxi. She probably compared the cost and benefits of packing lunch vs going to a restaurant before taking the final decision.
