Question

which of these do humans use the most for their source of drinking water? ice caps and glaciers; surface water & ground water; the oceans; the atmosphere

Explanation:

Ice caps and glaciers are mostly frozen and not easily accessible for direct drinking water use. Oceans have saltwater, which is not suitable for drinking without desalination (a less common primary source). The atmosphere has very little water available for direct use. Surface water (like lakes, rivers) and groundwater (aquifers) are the primary sources humans use for drinking water as they are more accessible and can be treated or used directly in many cases.

Answer:

B. surface water & ground water
