C. Assertion is true , Reason is false
D. Assertion is false , Reason is true .

Answer

To analyze the assertion and reason provided in the question, we will break down the concepts of nuclear forces and Coulombic interactions step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Nuclear forces arise from strong Coulombic interactions between protons and neutrons."
- **Analysis**: This statement is incorrect. Nuclear forces are not derived from Coulombic interactions. Coulombic forces are electromagnetic forces that arise due to the electric charge of particles (like protons). Nuclear forces, on the other hand, are a different type of force that acts at very short ranges (on the order of 10^-15 meters) and are responsible for holding the nucleus together.

2. **Understanding the Reason**:
- The reason states that "Nuclear forces are independent of the charge of the nucleons."
- **Analysis**: This statement is correct. Nuclear forces (strong nuclear forces) do not depend on the charge of the nucleons (protons and neutrons). They act between all nucleons regardless of whether they are positively charged (protons) or neutral (neutrons). The nuclear force is always attractive and is responsible for binding protons and neutrons together in the nucleus.

3. **Conclusion**:
- Since the assertion is false and the reason is true, we can conclude that the correct relationship is that the assertion does not accurately describe nuclear forces, while the reason correctly describes an important characteristic of nuclear forces.

### Final Answer:
- The assertion is false, and the reason is true.
