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 both the assertion (A) and the reason (R) provided.

### Step-by-Step Solution:

1. **Understanding Assertion (A)**:
- The assertion states: "Quark-quark force is said to be a fundamental force instead of strong nuclear force."
- We need to determine if this statement is true or false.
- In physics, the four fundamental forces are gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force. The strong nuclear force is the force that holds nucleons (protons and neutrons) together in the nucleus. The quark-quark force is a component of the strong nuclear force, as quarks are the building blocks of nucleons. Therefore, saying that the quark-quark force is a fundamental force instead of the strong nuclear force is incorrect.

2. **Understanding Reason (R)**:
- The reason states: "Nucleons consist of more fundamental particles known as quarks."
- This statement is true. Nucleons (protons and neutrons) are indeed made up of quarks, which are fundamental particles. Protons are made of two up quarks and one down quark, while neutrons are made of one up quark and two down quarks.

3. **Conclusion**:
- Since assertion (A) is false and reason (R) is true, we need to determine the relationship between them. The reason does not support the assertion because the assertion itself is incorrect.
- Therefore, the correct option is that both the assertion and the reason are false.

### Final Answer:
The correct option is 4: Both A and R are false statements.
