Electricity can be generated on a large scale from

Options

A. coal
B. ice
C. cables
D. all (a) , (b) , and (c ) .

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the sources from which electricity can be generated on a large scale.

2. **Identifying the Options**: The options provided include Coal, Water, Ice, and Cables. We need to evaluate which of these can generate electricity on a large scale.

3. **Analyzing Coal**: Coal is a fossil fuel that can be burned to produce heat. This heat is used to convert water into steam, which then drives turbines to generate electricity. Historically, coal has been a primary source for large-scale electricity generation.

4. **Analyzing Water**: Water can also generate electricity, particularly through hydroelectric power plants. In these plants, water is stored in dams and released to turn turbines, generating electricity. This is also a large-scale method of electricity generation.

5. **Analyzing Ice**: Ice itself does not generate electricity. It is simply frozen water and does not have the properties needed to produce electricity.

6. **Analyzing Cables**: Cables are used to transmit electricity but do not generate it. They are a means of conducting electricity from one place to another.

7. **Conclusion**: Based on the analysis, both coal and water can generate electricity on a large scale. However, since the question seems to focus on a single option, coal is often highlighted as a traditional source of large-scale electricity generation.

8. **Final Answer**: Therefore, the correct answer is **Coal**.
