Glass, metals, ceramics are the example of

Options

A. non-combustible materials
B. combustible materials
C. transparent
D. none of the above

Answer

To solve the question, "Glass, metals, ceramics are examples of," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Materials**: The question lists glass, metals, and ceramics. We need to categorize these materials based on their properties.

2. **Understand the Properties**:
- **Glass**: It is a solid material that is typically transparent and does not burn in the presence of air.
- **Metals**: These are solid materials that are generally good conductors of heat and electricity and do not combust easily.
- **Ceramics**: These are typically hard, brittle materials that are also non-combustible.

3. **Define Non-Combustible Materials**: Non-combustible materials are those that do not ignite or burn when exposed to fire or high temperatures. They do not produce heat and light when burned.

4. **Evaluate the Options**:
- **Option 1: Non-combustible materials** - This fits because glass, metals, and ceramics do not burn.
- **Option 2: Combustible materials** - This is incorrect as these materials do not burn.
- **Option 3: Transparent materials** - While glass is transparent, metals and ceramics are not, making this option incorrect.

5. **Conclusion**: The correct answer is that glass, metals, and ceramics are examples of non-combustible materials.

### Final Answer:
**Glass, metals, ceramics are examples of non-combustible materials.**
