A few properties are listed as:
(i) Form acidic oxides (ii) Produce sound on hitting (iii) High tensile strength (iv) Low density (v) Brittle
The properties shown by non-metals are

Options

A. (i), (ii) and (v) only
B. (iii) and (iv) only
C. (i), (iv) and (v) only
D. (iii) and (v) only

Explanation

To determine which properties are shown by non-metals from the given list, we will analyze each property one by one.

### Step-by-Step Solution:

1. **Form Acidic Oxides**:
- Non-metals typically form acidic oxides. For example, carbon dioxide (CO2) is an oxide of carbon, which is a non-metal, and it is acidic in nature.
- **Conclusion**: This property is correct for non-metals.

2. **Produce Sound on Hitting**:
- Non-metals are generally non-sonorous, meaning they do not produce sound when struck. Metals, on the other hand, are sonorous.
- **Conclusion**: This property is incorrect for non-metals.

3. **High Tensile Strength**:
- Non-metals usually have low tensile strength compared to metals. Metals are known for their ability to withstand tension without breaking.
- **Conclusion**: This property is incorrect for non-metals.

4. **Low Density**:
- Non-metals typically have lower densities compared to metals. For example, gases like oxygen and nitrogen are non-metals and have very low densities.
- **Conclusion**: This property is correct for non-metals.

5. **Brittle**:
- Non-metals are often brittle, meaning they can break easily when subjected to stress. For example, sulfur and phosphorus are non-metals that can break when hit.
- **Conclusion**: This property is correct for non-metals.

### Summary of Findings:
- The properties that are shown by non-metals from the list are:
1. Form acidic oxides (Correct)
2. Produce sound on hitting (Incorrect)
3. High tensile strength (Incorrect)
4. Low density (Correct)
5. Brittle (Correct)

### Final Answer:
The properties shown by non-metals are:
- (i) Form acidic oxides
- (iv) Low density
- (v) Brittle

Therefore, the correct option is the one that includes properties (i), (iv), and (v).
