How does vegetation near a river get water?

Correct answer: From the river and nearby moisture

The direct answer is A, vegetation near a river gets water from the river and nearby moisture. Plants need water for germination, photosynthesis, nutrient transport and maintaining their tissues. Step by step: river water may flow nearby or seep into the surrounding soil; the river can also raise local soil moisture and sometimes support groundwater; plant roots absorb available water from the soil; nearby vegetation therefore benefits from river water and moisture in the local environment. Option A is correct because it gives the relevant natural sources. Option B, only from the Moon, is false: the Moon affects tides and other phenomena but does not supply plant water. Option C, only from stones, is false; stones may hold some moisture in spaces but are not the sole water source. Option D, from smoke, is scientifically false and smoke can pollute rather than nourish plants. Not every plant receives water directly from the river, and rainfall may also contribute; the question asks for the normal relationship. Memory cue: rivers support nearby moisture, and roots take available water from soil.
