Janice wants to use a descriptive research method to study the behavior of children following the birth of a new brother or sister.She could use any of the following EXCEPT a(n)

A) case study.
B) observational study.
C) experiment.
D) survey.

Descriptive research methods, such as case studies, observational studies, and surveys, aim to observe, describe, and document aspects of a situation as it naturally occurs without manipulating the environment or variables. An experiment, however, involves manipulating one variable to determine if changes in one variable cause changes in another variable, which does not align with the descriptive nature of the research Janice intends to conduct.
