Hence, the correct option is II. Pulmonary edema occurs when interstitial fluid accumulates in tissues of the lung.

II. Pulmonary edema occurs when interstitial fluid accumulates in tissues of the lung

Explanation:

Pulmonary edema occurs when fluid enters into the lungs and accumulate. It a situation that occur when air do not enter into the alveoli( air sac) but fluid enters an accumulate in the air sac leading to shortage of oxygen in the blood stream.

Symptoms ranges from,
