B. Not conduct
C. Conduct partially
D. Break down

Answer

To solve the question regarding the behavior of a semiconductor diode when the p-side is earthed and the n-side is applied a potential of -2V, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Configuration**:
- The p-side of the diode is earthed, which means it is at 0 volts.
- The n-side is applied a potential of -2 volts.

2. **Determine the Voltages**:
- Let’s denote the voltage at the p-side (VA) as 0V (since it is earthed).
- The voltage at the n-side (VB) is -2V.

3. **Compare the Voltages**:
- We need to compare VA and VB:
- VA = 0V (p-side)
- VB = -2V (n-side)
- Since VA (0V) is greater than VB (-2V), we have:
- VA > VB.

4. **Analyze the Biasing Condition**:
- In a p-n junction diode, if the p-side is at a higher potential than the n-side, the diode is said to be in forward bias.
- In this case, since VA > VB, the diode is forward biased.

5. **Conclusion**:
- A forward-biased diode allows current to flow through it. Therefore, the diode will conduct electricity.

### Final Answer:
The diode shall conduct (Option 1).
