Step-by-step explanation:
Supreme Court justices are appointed for a term of life, making 'c' the correct answer to the original question posed. The current Supreme Court consists of one chief justice and eight associate justices. These justices are nominated by the president and must be confirmed by the Senate.
The first Supreme Court in 1789 had six justices, but since 1869, the number has been set at nine. While there has been discussion about expanding this number, there have been no changes since then. It's important to understand that although the Constitution established the Supreme Court, it does not specify the number of justices; this is left to Congress to determine. In contrast, states like Michigan have a set number of justices who serve fixed terms, which differs from the federal lifetime appointment.
