The correct response to the question is based on the process known as infiltration, which is crucial in the water cycle and in replenishing groundwater resources. Infiltration is the process through which water from rainfall penetrates the soil's surface and moves downward into the ground. As water falls during precipitation, some of it seeps through the soil pore spaces, which allows it to be stored in the ground and support plant life and ecosystems.

Infiltration is influenced by various factors such as soil composition, structure, moisture levels, and vegetation cover. The more permeable the soil (for example, sandy soils allow for greater infiltration compared to clay soils), the more efficiently water can be absorbed. This process plays a vital role in aquifer recharge and maintaining freshwater supplies, ultimately contributing to the overall health of the watershed.

In contrast, absorption refers to the uptake of water by plant roots, which is a different action that occurs after infiltration has taken place. Condensation pertains to the conversion of water vapor back into liquid water, typically forming clouds, and evaporation is the process of water turning from liquid to vapor, which occurs before precipitation. Both condensation and evaporation are essential components of the water cycle, but they are not directly involved in the absorption of water by the
