The closed-world assumption states that if a statement is not a consequence of information in the database, then it must be false. This means that any information not contained in the database is assumed to be false. Option A implies that the database is incomplete, which is not a part of the closed-world assumption. Option B is not correct because the closed-world assumption does not assume that everything in the database is universally true. Option D is incorrect because the closed-world assumption does not imply that the database contains all information known to humans.
