Hmm not sure but I would give a explanation..
Answer:
B) aorta to smaller systemic arteries to systemic capillaries to systemic veins to right atrium through the triscupid valve
Explanation:
Oxygenated blood from the right ventricle is pumped into the aorta. Aorta is the largest systemic artery that obtains oxygenated blood directly from the heart. Many systemic arteries get oxygenated blood from the aorta. Exchange of oxygen between blood and tissue cells occurs in systemic capillaries.
The deoxygenated blood from tissues is picked by systemic veins. The deoxygenated blood from systemic veins is delivered to the right atrium via vena cava. The blood is pumped from the right atrium to the right ventricle through the tricuspid valve from where it is carried to the lungs for oxygenation. The oxygenated blood from the left atrium is pumped to the left ventricle and finally into the aorta.

any baby who is a healthy child should be put to sleep on his/her back rather
than on their stomach or sides by their mothers or whosoever takes care of
them. This practice is really useful to lessen the dangers of sudden infant
death syndrome.</span>
