The correct answer is A. Society’s expectations and laws.
Step-by-step explanation:
According to Kolhberg, who proposed a theory regarding moral development, humans go through three main stages to develop moral: the pre-conventional stage, the conventional stage, and the post-conventional stage.
The conventional stage occurs after childhood and implies acting or making moral decisions based on the conventions of society (standards, views, laws, expectations). This occurs because the individual understands the importance of fitting in society, and following laws or standards to preserve the equilibrium in society. This implies in this stage moral decisions are based on "Society’s expectations and laws".
