(B) The human heart functions as a double pump system:$1$. The left atrium receives oxygenated blood from the lungs via pulmonary veins,not from the body. Thus,statement $(i)$ is false.$2$. The left ventricle pumps oxygenated blood to the entire body through the aorta,and the right ventricle pumps deoxygenated blood to the lungs for oxygenation. Thus,statement $(ii)$ is true.$3$. The left atrium transfers oxygenated blood to the left ventricle,not the right ventricle. Thus,statement $(iii)$ is false.$4$. The right atrium receives deoxygenated blood from the body,and the left ventricle pumps oxygenated blood to the body. Thus,statement $(iv)$ is true.Therefore,statements $(ii)$ and $(iv)$ are correct.
