Pouring water method should never be used for electrical fires, as water is a good conductor of _____.

Options

A. Electricity
B. Heat
C. Light
D. Both (a) and (b)

Answer

To solve the question, we need to identify what water conducts that makes it dangerous to use on electrical fires.

### Step-by-Step Solution:

1. **Understanding the Question**: The question states that pouring water should never be used for electrical fires. We need to fill in the blank with what water is a good conductor of.

2. **Knowledge of Water Properties**: Water is known to be a good conductor of certain substances. In the context of electrical fires, we need to think about what type of energy or force could be conducted.

3. **Identifying Conductivity**: Water conducts electricity. This means that if water is poured on an electrical fire, it can allow electric current to flow through it, which can lead to electric shock or further spreading of the fire.

4. **Final Answer**: Therefore, the blank in the question can be filled with "electricity". The complete statement would be: "Pouring water method should never be used for electrical fires, as water is a good conductor of electricity."
