Answer :
The person who objects to war on the basis of higher moral principles and a personal code of ethics would be said to be at postconventional levels of moral development (Option A).
Postconventional morality was a concept developed by American psychologist Lawrence Kohlberg. The concept identifies the ethical reasoning of moral individuals who make decisions based on values, rights, duties, or principles that are universalizable. An example would be the belief that healthcare should be universally held in the United States. In moral development, the postconventional stage means that an individual progress beyond the perspective of their society and attempts to consider the perspective of all individuals. A person objecting to war on the basis of higher moral principles and ethics hence is in the postconventional level.
