Answer:
Option D
Step-by-step explanation:
Among the options there in the comments, I'm assuming we want to choose people for authority like political positions or simply positions to give orders and have different functions.
Now, option a) can be easily discarted because the prettiest person or even the stronger in option b), does not mean that the person can be trustable and have great authority to command and lead groups of people. In real life, Prettiest people it's not always associated with authority. So both options are discarted.
Option c) son or daughter of the current person with authority, doesn't mean that he or she is capable to do authority or have all the competence, characteristic, and qualities to be a leader and lead group of people with authority.
Therefore, it's always the best to run a free and fair election, when different candidates can show their skills, qualities and reason of why they can be the person whom they can trust and choose to be their leader or person with authority. So option D.
