Solution

The correct option is B Both a and b
Lungs receive blood from the right side of the heart, whereas the branching of systemic arteries results in a parallel pattern. This system has many advantages. It ensures that each of the peripheral organs and tissues receives only a fraction of blood pumped by the left ventricle and it allows for independent variation in blood flow through different tissues as an individual's metabolic activities change.
Thus, the correct answer is 'Both a and b'.
