Which of the following is a secondary function of education?

The correct answer is A. Social Control.

Explanation: While socialization (B) is considered a primary function of education as it helps integrate individuals into society by teaching norms and values, social control refers to maintaining order and conformity within a society. This is a secondary function of education, as it helps regulate behavior and ensure that societal norms are upheld. Standardized testing (C) and courtship (D) may have roles in educational systems but are not primary functions of education itself.
