Explanation:

D. Our sense of what is right or wrong is not an instinctive part of us.

Explanation:

During personality development, from the earliest days, people learn what is right and what is bad. Therefore, what is wrong or right is not a part of us; it is the moral values we acquire throughout life. Children from the earliest years of moral value learn through their parents. The proper guidance of the child is crucial for its development. Therefore, if a child begins to act on the issue of morality wrong, parents need to point it out. Likewise, for good. Therefore, these "techniques" are not innate; they are learned.
