Given below are two statements:
Statement I : In a typical transistor, all three regions emitter, base and collector have same doping level.
Statement II : In a transistor, collector is the thickest and base is the thinnest segment. In the light of the above statements, choose the most appropriate answer from the options given below

Options

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

Answer

To solve the given problem, we need to analyze both statements regarding the characteristics of a typical transistor.

### Step 1: Analyze Statement I
- **Statement I**: "In a typical transistor, all three regions (emitter, base, and collector) have the same doping level."
- In a typical bipolar junction transistor (BJT), the three regions do not have the same doping levels. The emitter is heavily doped to inject carriers efficiently, the base is lightly doped to allow for carrier movement, and the collector is moderately doped. Therefore, this statement is **false**.

### Step 2: Analyze Statement II
- **Statement II**: "In a transistor, the collector is the thickest and the base is the thinnest segment."
- This statement is true. In a BJT, the collector region is designed to be the thickest to handle the majority of the current, while the base region is the thinnest to allow for efficient carrier recombination and transport. Thus, this statement is **true**.

### Step 3: Conclusion
- Since Statement I is false and Statement II is true, we can conclude that the correct answer is that Statement I is incorrect and Statement II is correct.

### Final Answer
- The most appropriate answer is **Option 4**: Statement I is false, and Statement II is true.
