More than 70% of world's fresh water is contained in

Options

A. Antarctica
B. Glaciers and mountains
C. Greenland
D. polar ice

Explanation

### Step-by-Step Solution:

1. **Understanding Fresh Water**: Begin by recognizing that fresh water is naturally occurring water that is not salty. It is essential for life and is found in various forms on Earth.

2. **Identifying Major Fresh Water Sources**: The question asks about the source that contains more than 70% of the world's fresh water. The primary sources to consider are Antarctica, Greenland, glaciers, and polar ice caps.

3. **Analyzing Antarctica**: Antarctica is known for its vast ice sheets. Approximately 61% of the fresh water on Earth is stored in these ice sheets. Since this is less than 70%, Antarctica cannot be the correct answer.

4. **Examining Greenland**: Greenland is the largest island in the world and is predominantly covered by ice. However, it is also not a significant source of fresh water compared to the total amount found in polar ice caps.

5. **Considering Glaciers**: Glaciers are large masses of ice that flow over land. While they do contain fresh water, they do not account for more than 70% of the world's fresh water supply.

6. **Evaluating Polar Ice Caps**: Polar ice caps, which include the ice sheets in both Antarctica and the Arctic regions, hold the majority of the Earth's fresh water. It is estimated that more than 70% of the world's fresh water is stored in these polar ice caps.

7. **Conclusion**: Based on the analysis, the correct answer to the question is that more than 70% of the world's fresh water is contained in the polar ice caps.

### Final Answer:
The correct option is **D) Polar Ice Caps**.
