Based on the word root, which word means "an official announcement"?

autocrat

credo

interdict

geodesic

The correct answer is "credo." The root "cred" means "to believe." The word credo means "an official statement of beliefs." The other options do not contain the root "cred" and do not mean "an official announcement." An autocrat is a tyrant or dictator; an interdict is a formal prohibition; and geodesic refers to lines on a sphere.
