Explanation:
Birds and mammals have a double circulatory system and a four-chambered heart which separates the oxygenated blood and the deoxygenated blood from each other in the heart. This system of circulation is necessary to serve the high energy needs of the mammals and birds.
In this system, deoxygenated blood from the body passes through the superior and inferior Vena Cava into the right atrium. From the right atrium it flows into the right ventricle. From the right ventricle, it is then pumped into the pulmonary artery to be carried to the lungs. In the lungs, the deoxygenated blood is oxygenated and returned to the heart through the pulmonary veins.
Oxygenated blood enters the left atrium from the lungs through the pulmonary veins. It then moves into the left ventricle. In the left ventricle, it is then pumped into the aorta. The aorta is a large vessel that runs the length of the vertebral column, branching off to be circulate blood in the body system.

the correct answer is option D). both species have gill slits when they are embryos.
Explanation:
A common ancestor of humans and fish denotes the most recent organism, from which both the humans and fish have been evolved. Humans and fishes are vertebrates, which possess spinal column or backbone. Along with this, human embryos also go through a stage, during which they have gill-slits like structures in their neck as present in fish embryos.
These structures do not found in mature humans like fishes, but they support the fact that the humans share a common ancestral organism with fish.
