Answer is Right!
Answer is Wrong!
The correct answer is C. The human heart has four chambers: two upper chambers called atria and two lower chambers called ventricles. The atria are smaller than the ventricles and receive blood from the body and lungs. The ventricles are larger than the atria and pump blood to the body and lungs.
Option A is incorrect because the human heart has four chambers, not two.
Option B is incorrect because the human heart has four chambers, not three.
Option D is incorrect because the human heart has four chambers, not five.
