Explanation
When babies are born, the first contact they have with other people is with their family, they learn to speak their first words, take their first steps and understand how society works. In it, their parents teach him/her how society is governed by laws that must be followed and what rights we have as citizens of a nation. In this scenario, the child begins to reason about the functioning of society and how to function in it. Also, parents teach children how to interact with other people, for example, children learn to greet kindly when they arrive at someplace, and to say goodbye once they leave. Also, they learn when another person is speaking they should not interrupt and they should take some precautions with unknown persons. So, the correct answer is D. In the family
