What is true about the number of justices on the Supreme Court? A. The number of justices on the Supreme Court changes every 4 or 8 years.
B. The Supreme Court can have up to 15 justices.
C. The number of justices on the Supreme Court has remained at nine since 1869.
D. Although not legally required, the number of justices on the Supreme Court has always been nine.
The correct answer is C. The number of justices on the Supreme Court has remained at nine since 1869.
Explanation: The number of justices on the U.S. Supreme Court was set to nine in 1869 and has not changed since then. While Congress has the power to alter the number of justices, it has remained stable at nine for over 150 years. Option D is also partially true, but C is more precise regarding historical context.
