A : Quark-quark force is said to be fundamental force instead of strong nuclear force.
R : Nucleons consist of more fundamental particles known as quarks.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).
C. If Assertion is true statement but Reason is false, then mark (3).
D. If both Assertion and Reason are false statements, then mark (4).

Answer

To solve the question, we need to analyze the two statements A and R regarding the quark-quark force and nucleons.

### Step 1: Analyze Statement A
- **Statement A**: "Quark-quark force is said to be a fundamental force instead of strong nuclear force."
- The fundamental forces in nature are gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force. The quark-quark force is indeed a part of the strong nuclear force, which acts between quarks. Therefore, this statement is incorrect because the quark-quark force is not classified as a separate fundamental force; it is a manifestation of the strong nuclear force.

### Step 2: Analyze Statement R
- **Statement R**: "Nucleons consist of more fundamental particles known as quarks."
- Nucleons (protons and neutrons) are indeed made up of quarks. However, the statement implies that quarks are the fundamental particles of the nucleus, which is misleading. While quarks are fundamental particles, nucleons themselves are not considered fundamental particles; they are composite particles made of quarks. Thus, this statement is also incorrect.

### Step 3: Conclusion
- Since both statements A and R are incorrect, we conclude that the correct answer is option 4, which states that both A and R are wrong.

### Final Answer
Both statements A and R are incorrect.
