Correct Answer: They have a two-chambered heart
Solution : The correct answer is They have a two-chambered heart
"They have a two-chambered heart" is incorrect for the class Aves of the animal kingdom. Birds (class Aves) have a four-chambered heart, which is a characteristic feature that distinguishes them from some other vertebrates. The four-chambered heart allows for more efficient separation of oxygenated and deoxygenated blood, facilitating the high metabolic demands associated with powered flight.
