Hint: A well is an excavation or device dug, driven, or drilled into the earth to reach liquid materials, most often water. A water well is the oldest and most popular kind of well.

Complete answer:
Let us look into the given options:
A) Surface water : Water that is found on top of the Earth's atmosphere, such as ponds, creeks, and lakes, is known as surface water. Blue water is another name for this kind of water. Precipitation and drainage from surrounding regions account for the vast majority. But we know that well water is not found on the surface. Hence, this option is incorrect.
B) Rain water : Rainwater management is the process of collecting and storing rainwater rather than letting it drain out. Rainwater is gathered from a roof-like surface and driven by percolation into a pool, cistern, deep pit, aquifer, or reservoir. Nets or other methods may also be used to capture dew and fog. But we know that well water is not collected from rain. Hence, this option is incorrect.
C) Underground water : Groundwater is the water that exists under the Earth's crust in the pore spaces of rocks and soils, as well as in the cracks of geological formations. When a unit of rock or an unconsolidated sediment will yield a usable amount of water, it is considered an aquifer. We know that well water is obtained by digging the surface to reach underground.Hence, this option is correct.
D) River water : For homes, irrigation, and industry, river water is an essential source of surface water. Rivers also have a variety of ecosystem services. The amount and condition of river water is heavily influenced by the drainage system, seasonal modifications, and the general soil and vegetation it passes through on its way to the sea. We know that well water is not surface water. Hence, the option is incorrect.

Therefore, option (C) Underground water is the correct answer.

Note: Since there are no additives applied to well water, it usually tastes better. Chlorine, iodine, and other harsh and hazardous additives are used to clean public water. Well water rises directly from the ground, providing all of the health advantages of pure water without the harsh chemical contaminants.
