Solution

The correct option is B Oxygenated and deoxygenated bloods mix up
Frog has three chambered heart with two atria and one ventricle. Left atrium receives oxygenated blood from the lungs while right atrium receives deoxygenated blood from the body. Both the atria empty into single ventricle due to which the blood get mixed up.
So the correct answer is 'Oxygenated and deoxygenated bloods mix up'.
