Similar associations arise through the school and the neighborhood,and through these institutions,the child learns ______.

A) equality
B) morality
C) ethics
D) principles

The most appropriate option here is "morality" because schools and neighborhoods usually indoctrinate children with basic moral principles and values. Ethics and principles are also taught in schools, but they are more advanced and require a higher level of cognitive understanding, which may not develop until later in a child's life. Equality is also an important value that may be taught, but it is not as universal or fundamental as morality.
