Answer:
Group A
Step-by-step explanation:
Group A is the correct option because the main role of the Judicial Branch is to evaluate laws, settle disagreements about what the law means and how should be enforced and declare the unconstitutionality of laws enacted by Congress or acts of the executive. Furthermore, when the judges, both of the supreme and inferior courts, are appointed, they are appointed to serve for life or until they resign or are dismissed.
