Civility is a characteristic that requires the individual to have a strong ethical sense. In this case, we can see that Gladys has ethics in her actions to help Andrew.
This is because ethics is the term that determines a person's social behavior based on what he believes to be right or wrong. For Gladys, helping people is the right thing to be done within the social environment, so it acts in an ethical manner. In addition, it refers to the ability of an individual to live within the established norms for the maintenance of social interaction, that is, civility is part of ethics.
The right answer is d. flatest and the proper spelling rule is to double the consonant when addix a suffix. The same happens in nouns/ adjectives like hot > hotter, jam > jamming.
