C Correct answer
Explanation

Approximately 68.7% of Earth's freshwater is stored in glaciers and ice caps, primarily in Antarctica and Greenland. The remaining freshwater is divided between groundwater (about 30%) and surface water like lakes and rivers (about 1.2%). This makes glaciers the planet's largest reservoir of freshwater, though most is inaccessible for human use and critical for regulating global climate and sea levels.
