What is not a state power in Germany?

EDITORIAL LEARNING AID

Why is this answer correct?

Under Article 20(2) of the Basic Law, state authority is exercised through legislation (parliament), executive power (government and administration) and the judiciary (courts). The press is not a state power; it is free and in private hands.

Three powers: legislature, government, judiciary — not the press.
