Options

A. Statement `1` is correct but statement II is correct
B. Both Statement I and Statement II are incorrect
C. Statement I is incorrect but statement II is correct
D. Both Statement I and statement II are correct

Answer

To solve the question, we need to analyze the two statements regarding the doping of silicon and the behavior of p-type and n-type semiconductors.

### Step-by-Step Solution:

1. **Understanding Doping in Semiconductors**:
- When silicon (Si) is doped with boron (B), it becomes a p-type semiconductor. This is because boron has one less valence electron than silicon, creating "holes" (positive charge carriers).
- When silicon is doped with arsenic (As), it becomes an n-type semiconductor. Arsenic has one more valence electron than silicon, providing excess electrons (negative charge carriers).

**Hint**: Remember that p-type semiconductors have holes as majority carriers, while n-type semiconductors have electrons as majority carriers.

2. **Analyzing Statement I**:
- The first statement correctly describes the behavior of silicon when doped with boron and arsenic.
- Therefore, Statement I is **correct**.

**Hint**: Confirm the definitions of p-type and n-type semiconductors to validate this statement.

3. **Analyzing Statement II**:
- The second statement claims that when p-type and n-type semiconductors are fused together, a current will automatically flow, which can be detected with an external ammeter.
- However, for current to flow, there must be a potential difference (voltage) or an external circuit connected. If there is no external battery or voltage source, the current will be zero.

**Hint**: Consider the conditions necessary for current flow in a circuit and the role of an external power source.

4. **Conclusion**:
- Since Statement I is correct and Statement II is incorrect, we conclude that the correct option is that Statement I is true, and Statement II is false.

**Final Answer**: Statement I is correct, and Statement II is incorrect.

### Summary of the Solution:
- Statement I: Correct (p-type has holes, n-type has electrons).
- Statement II: Incorrect (current does not flow without an external power source).

### Final Answer:
- **Option**: Statement I is correct, Statement II is incorrect.
