Question

always be applied to the
states by the court.
sometimes be applied to
the states by the court.
sometimes be applied to
the court by the states.
never be applied to the
states by the court

Explanation:

Selective incorporation is a legal doctrine where the Supreme Court applies parts of the Bill of Rights to the states through the Due Process Clause of the 14th Amendment. It is not an all - or - nothing application. The Court has gradually incorporated certain rights over time, not all at once. So, it's a matter of sometimes applying the Bill of Rights to the states, not always, never, or the states applying to the Court.

Answer:

sometimes be applied to the states by the Court.
