A child caregiver who is using the statement, "Say please," is practicing _______ socialization.

 A. external B. internal C. intentional D. unintentional

 C.

The correct answer is C. intentional socialization.

To arrive at this answer, we need to understand the different types of socialization and their definitions.

Socialization refers to the process through which individuals learn and develop behaviors and attitudes that are appropriate for their society or culture. It is a lifelong process that begins in childhood and continues throughout one's life.

There are different types of socialization, including external and internal socialization. External socialization refers to the social influences that come from outside sources, such as parents, family members, friends, and society at large. Internal socialization, on the other hand, refers to the process through which individuals internalize and incorporate these external influences into their own thoughts, attitudes, and behaviors.

In this context, a child caregiver who is using the statement "Say please" is engaging in intentional socialization. By encouraging the child to use polite language and say "please," the caregiver is deliberately trying to teach the child appropriate social behavior. The caregiver is intentionally shaping the child's social skills and teaching them how to interact politely with others.

Thus, the correct answer is C. intentional socialization.
