The fourth answer is correct (D).
The judges of the Supreme Court represent the apex of the hierarchy of the Judiciary. In this way, they are responsible for analyzing the constitutionality of proposals and analyzing special cases through deliberation.
Deliberation takes place when a new fact occurs over a previous deliberation or when a matter not yet discussed reaches the court. Thus, the judges discuss the points and vote. The majority decision becomes applicable in the legal system of the country.
