Children's popularity among peers is assessed with a. sociometric techniques. b. a prospective study. c. meteorological assessment of cross-pressures. d. evaluations of their mean-world beliefs.

A

Explanation:

J.L Moreno and Hellen Jennings in 1960 developed the sociometric techniques. They use it to present simple graphical social relationships, friendship patterns, attractions and rejections which exist at a given time among different people. Sociometric techniques qualitatively measures different part of social acceptance  and social status of a person among their peers for example a child's social status among his/her peers.

the correct answer is individualism and exchange. at this stage, children begin to question the rules, because they can see that there is more than one side to them. different individuals have different viewpoints. they won't be able to reach this stage because of ignorance, a lack of ethics or personal biases. that is because people with that characteristiscs are not able to distinguish what is good or what is bad and they can't pursue their individual interests.
