Answer:
C
Step-by-step explanation:
The president has the power to nominate the Supreme Court justices but to do so 2/3 of the senate only not the house of representatives have to approve the appointment. Take the nomination of Justice Amy Coney Barret for example President Trump nominated her for the Supreme Court and relativey quickly 2/3 of senate approved and she was appointed. If senate had not given a 2/3 vote Justice Amy Barret would not have become part of the Supreme Court. This is one of congress' checks and balances.
