Evidence suggests that locus of control is learned in childhood and is directly related to

A) positive reinforcement.
B) peer pressure.
C) parental behavior.
D) culture.

Research has consistently shown that parental behavior is a significant factor in the development of locus of control. Children who receive consistent support, encouragement, and autonomy from their parents are more likely to develop an internal locus of control, while children who experience high levels of control or neglect from their parents are more likely to develop an external locus of control. Therefore, option C is the best choice.
