Correct answer: C

If the statement 'Some animals are not birds' is false, its contradictory 'All animals are birds' must be true. This validates statement A directly. Additionally, universal affirmative statements imply particular affirmatives in traditional logic, confirming that 'Some animals are birds' is also true. Consequently, statements B and C must be false as they contradict the universal claim.
