Step-by-step explanation:
- Appointed by the president
- Approved by the Senate
To become a Supreme Court Justice, the president of the United States appoints an individual to the position. This appointment is subject to approval by the Senate. Once the Senate confirms the president's nominee, the individual officially becomes a Supreme Court Justice.
The other options mentioned in the question, such as being appointed by Congress and approved by the president or being appointed by the Judicial Branch and approved by Congress, are not accurate. The process of appointing and approving Supreme Court Justices involves the president and the Senate.
