The maximum amount of oxygen is exchanged from "blood in the capillaries surrounding the tissue cells".

Answer: Option(a)

The blood carries the oxygen into capillaries. The oxygen in the capillaries is transported to enrich the tissue with a good amount of oxygen and also to make them strong and active in functional quality.

The oxygen plays a major role in various biochemical pathway. Hence the oxygen is exchanged from the blood into tissue cells.
