C,D Correct answer
Explanation

A blue whale's heart is enormous - typically around 600 kg and can reach 900 kg in exceptional cases, making it the largest heart of any animal. The aorta is remarkably wide at about 23 cm in diameter, allowing massive blood flow. Options A and B are incorrect because the tongue weighs ~2,700 kg (not 2.7 kg) and the mouth can hold ~90 metric tons (not kg).
