Given below are two statements :
Statement I : PN junction diodes can be used to function as transistor, simply by connecting two diodes, back to back, which acts as the base terminal.
Statement II : In the study of transistor, the amplification factor B indicates ratio of the collector current to the base current.
In the light of the above statements, choose the correct answer from the options given below:

Options

A. Statement I is false but Statement II is true
B. Both Statement I and Statement II are true
C. Both Statement I and Statement II are false
D. Statement I is true but Statement II is false

Answer

To solve the question, we need to analyze the two statements provided:

### Step 1: Analyze Statement I
**Statement I**: "PN junction diodes can be used to function as a transistor simply by connecting two diodes, back to back, which acts as the base terminal."

1. **Understanding Transistors**: A transistor is a three-terminal device (Emitter, Base, Collector) that can amplify current. In contrast, a PN junction diode is a two-terminal device.
2. **Connecting Diodes**: If we connect two diodes back to back, we do not create a proper transistor. The base region of a transistor should be thin and lightly doped, which is not the case when connecting two diodes.
3. **Atomic Level Contact**: For a transistor to function, the junctions must be formed at an atomic level, which cannot be achieved just by physically connecting two diodes.
4. **Conclusion**: Therefore, Statement I is **false**.

### Step 2: Analyze Statement II
**Statement II**: "In the study of transistor, the amplification factor β indicates the ratio of the collector current to the base current."

1. **Understanding the Amplification Factor**: The amplification factor (β) of a transistor is defined as the ratio of the change in collector current (ΔIc) to the change in base current (ΔIb).
2. **Mathematical Representation**: β = ΔIc / ΔIb.
3. **Conclusion**: Therefore, Statement II is **true**.

### Step 3: Determine the Correct Option
Based on the analysis:
- Statement I is **false**.
- Statement II is **true**.

Now we can choose the correct answer from the options provided. The correct option would be the one that states that Statement I is false and Statement II is true.

### Final Answer
The correct option is the one that states: **Statement I is false, Statement II is true.**
