Given below are two statements.

Statement I: The partial pressure gradient for O₂ favours the diffusion of O₂ from alveoli to blood and blood to tissues.

Statement II: The partial pressure gradient for CO₂ favours the diffusion of CO₂ from tissues to blood and blood to alveoli.

In light of the above statements, choose the correct answer from the options given below. 

The partial pressure gradient for O₂ favours the diffusion of O₂ from alveoli (104 mm Hg) to deoxygenated blood in the pulmonary capillaries (40 mm Hg) and from oxygenated blood in systemic capillaries (95 mm Hg) to tissues (40 mm Hg).

The partial pressure gradient for CO₂ favours the diffusion of CO₂ from systemic tissues (45 mm Hg) to oxygenated blood in systemic capillaries (40 mm Hg) and from deoxygenated blood in pulmonary capillaries (45 mm Hg) to alveoli (40 mm Hg).
