Which of the following pairs does not show same electrical property ?

Options

A. Copper and Aluminium
B. Air and human body
C. Silver and steel
D. Distilled water and mica

Explanation

To determine which of the following pairs does not show the same electrical property, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Options**: We need to look at the pairs provided in the question. The options are:
- Option 1: Copper and Aluminum
- Option 2: Air and Human Body
- Option 3: Silver and Steel
- Option 4: Distilled Water and Water

2. **Analyze Option 1 (Copper and Aluminum)**:
- Both copper and aluminum are metals that conduct electricity.
- **Conclusion**: They both show the same electrical property (conductors).

3. **Analyze Option 2 (Air and Human Body)**:
- Air is an insulator, meaning it does not conduct electricity.
- The human body, on the other hand, is a conductor of electricity.
- **Conclusion**: They do not show the same electrical property (one is an insulator, the other is a conductor).

4. **Analyze Option 3 (Silver and Steel)**:
- Both silver and steel are conductors of electricity. Silver is known for its excellent conductivity, while steel is a good conductor but not as good as silver.
- **Conclusion**: They both show the same electrical property (conductors).

5. **Analyze Option 4 (Distilled Water and Water)**:
- Distilled water is generally considered a poor conductor of electricity (an insulator), while regular water (especially if it contains impurities) can conduct electricity.
- **Conclusion**: They do not show the same electrical property (one is an insulator, the other can be a conductor).

6. **Final Conclusion**:
- The pairs that do not show the same electrical properties are:
- Option 2: Air and Human Body
- Option 4: Distilled Water and Water
- However, since the question asks for a single pair, the most distinct difference is found in Option 2.

### Answer:
The correct answer is **Option 2: Air and Human Body**, as they do not show the same electrical properties.
