B. Assertion and reason both are correct statement but reason is not correct explanation for assertion
C. Assertion is correct statement but reason is wrong statement.
D. Assertion is wrong statement but reason is correct statement

Answer

To solve the question regarding the assertion and reason about equilibrium, let's break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Equilibrium is dynamic in nature." This means that at equilibrium, the forward and reverse reactions occur at the same rate. Therefore, even though the concentrations of reactants and products remain constant, the reactions continue to occur.

**Hint**: Think about what "dynamic" means in the context of reactions. It implies ongoing processes rather than a static state.

2. **Understanding the Reason**: The reason provided states that "The concentrations of reactants and products become equal at equilibrium." This is a common misconception. In reality, the concentrations of reactants and products do not have to be equal at equilibrium; they simply reach a constant ratio defined by the equilibrium constant (K).

**Hint**: Consider examples of chemical reactions where the amounts of reactants and products are not equal at equilibrium.

3. **Analyzing the Relationship**: Since the assertion is true (equilibrium is dynamic), we must evaluate the reason. The reason is false because equilibrium does not require equal concentrations of reactants and products. The equilibrium constant (K) is determined by the ratio of concentrations, which can vary.

**Hint**: Recall that the equilibrium constant expression is based on the concentrations of products and reactants raised to their respective stoichiometric coefficients.

4. **Conclusion**: Based on the analysis:
- The assertion is correct: Equilibrium is indeed dynamic.
- The reason is incorrect: Concentrations of reactants and products do not need to be equal at equilibrium.

Thus, the final answer is that the assertion is true, but the reason is false.

### Final Answer:
- Assertion: True
- Reason: False
- Therefore, the correct answer is C (Assertion is correct, Reason is incorrect).
