Final answer:
Moderate hypertension can cause damage to the kidneys and the brain due to high blood pressure leading to conditions like nephropathy and stroke, but lung damage is not typically caused by moderate hypertension.
Step-by-step explanation:
Moderate hypertension can indeed cause damage to multiple organs due to the increased pressure exerted on the vessel walls. Among the organs that can be affected are the kidneys and the brain. The kidneys may suffer from conditions such as nephropathy, which is a form of kidney damage that results from high blood pressure. Similarly, the brain can be affected by hypertension through the risk of strokes or hypertensive encephalopathy. However, while hypertension can lead to pulmonary edema, which does involve the lungs, the damage to the lung tissues is not typically caused by moderate hypertension, but rather by more acute or severe conditions.
The correct answer to the student's question is that moderate hypertension can produce damage to the kidneys and the brain, so the choice would be 'kidneys and brain only' (option not provided explicitly in the question).
