Question

what is socialization?
the process of teaching children how to behave in society
the study of social behavior from a biological perspective
the lifelong process of social interaction through which individuals acquire a self - identity and the skills needed for survival in society
the process of learning new skills for a specific job

Explanation:

Socialization is a lifelong process. It's not just limited to childhood (so the first option is too narrow). It's not about a biological study of social behavior (eliminating the second option). And it's not job - specific skill learning (fourth option out). It involves social interaction where individuals gain self - identity and societal survival skills.

Answer:

The lifelong process of social interaction through which individuals acquire a self - identity and the skills needed for survival in society.
