Options
- A(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
- B(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
- C(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
- D(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
Correct answer
C. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Step-by-step solution
According to NCERT, the sinus venosus is a triangular structure that joins the right atrium (A-III). The ventricle opens into a sac-like conus arteriosus on the ventral side of the heart (B-IV). The special venous connection between the liver and intestine is called the hepatic portal system (C-I). The special venous connection between the lower parts of the body and the kidney is called the renal portal system (D-II). Therefore, the correct matching is (A)-(III), (B)-(IV), (C)-(I), (D)-(II). Answer: (A)-(III), (B)
