Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R
Assertion A: The beam of electrons show wave nature and exhibit interference and diffraction.
Reason R : Davisson Germer Experimentally verified the wave nature of electrons.
In the light of the above statements, choose the most appropriate answer from the options given below:

Options

A. A is correct but R is not correct
B. Both A and R are correct but R is Not the correct explanation of A
C. Both A and R are correct and R is the correct explanation of A
D. A is not correct but R is correct

Answer

To solve the given question, we need to analyze the two statements: Assertion A and Reason R.

### Step 1: Understand Assertion A
Assertion A states that "The beam of electrons shows wave nature and exhibits interference and diffraction."
- This statement is true. According to quantum mechanics, electrons can exhibit wave-like behavior, which allows them to show phenomena such as interference and diffraction, similar to light waves.

### Step 2: Understand Reason R
Reason R states that "Davisson Germer experimentally verified the wave nature of electrons."
- This statement is also true. The Davisson-Germer experiment was a pivotal experiment in demonstrating the wave nature of electrons. It showed that electrons can exhibit diffraction patterns, which is a characteristic of waves.

### Step 3: Analyze the Relationship Between A and R
Now we need to determine if Reason R provides an explanation for Assertion A.
- Since the Davisson-Germer experiment confirmed the wave nature of electrons, it directly supports the idea presented in Assertion A that electrons exhibit wave-like behavior.

### Conclusion
Both Assertion A and Reason R are true, and Reason R is indeed the explanation for Assertion A. Therefore, the correct conclusion is:

**Assertion A is true, Reason R is true, and R is the correct explanation of A.**

### Final Answer
The correct option is: **3. A and R are correct, and R is the correct explanation of A.**
