The correct answer is: B.Water in the air (atmosphere)

Explanation:

Water vapor refers to water in its gaseous state, which is present in the air or atmosphere. It is a key part of the water cycle, as water evaporates from the Earth's surface (such as oceans, lakes, and rivers) and enters the atmosphere as water vapor. This vapor can then condense into clouds and eventually return to the Earth as precipitation.

Why the other options are incorrect:

A.Water on the land (geosphere): This refers to water found on land in lakes, rivers, and streams, but water vapor is not in liquid form on the land.
