Greater capillary density improves which tissue processes?

Explanation:
Increasing capillary density expands the network of tiny vessels where exchange happens between blood and tissues. With more capillaries, there is more surface area and the distance from a capillary to surrounding cells is shorter, which makes diffusion of oxygen into cells faster and the removal of waste products like carbon dioxide more efficient. That combination directly enhances both oxygen delivery to tissues and the removal of metabolic wastes, which is exactly what the option describes. The other ideas don’t fit: simply more capillaries doesn’t inherently decrease oxygen delivery or reduce metabolic waste production, and it doesn’t directly cause lower blood pressure.
