Assertion : In amphibians, the heart is two chambered. Reason : The deoxygenated and oxygenated blood is returned to the heart through the sinus venosus.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Amphibians have a three-chambered heart. The three-chambered heart consists of two atria and one ventricle. Both atria empty into the single ventricle, mixing the oxygenrich blood returning from the lungs with the oxygen-depleted blood from the body tissues. Thus, both Assertion and Reason are false.

4 Hirudinaria
Explanation:
Open circulatory system is present in arthropods and molluscs in which blood pumped by the heart passes through large vessels into open spaces or body cavities called sinuses. Periplaneta (cockroach) an arthropod has an open circulatory system.
