B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-4
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

To solve the question, we need to evaluate the two statements provided:

**Statement 1:** At low concentration, benzene and toluene form an ideal solution.

**Statement 2:** Components with structural similarities form ideal solutions.

### Step-by-Step Solution:

1. **Understanding Ideal Solutions:**
- An ideal solution is one that obeys Raoult's law, which states that the vapor pressure of each component in a solution is directly proportional to its mole fraction in the solution.

2. **Analyzing Statement 1:**
- Benzene (C₆H₆) and toluene (C₆H₅CH₃) are structurally similar compounds.
- At low concentrations, the interactions between the molecules of benzene and toluene are similar to the interactions between the molecules of each component (benzene-benzene and toluene-toluene).
- Therefore, at low concentrations, benzene and toluene do indeed form an ideal solution as they obey Raoult's law.

3. **Analyzing Statement 2:**
- This statement claims that components with structural similarities form ideal solutions.
- Benzene and toluene, having similar structures, exhibit similar intermolecular forces, which supports the idea that they will form an ideal solution.
- Thus, this statement is also true.

4. **Evaluating the Relationship Between the Statements:**
- Statement 1 is true because benzene and toluene form an ideal solution at low concentrations.
- Statement 2 is true as well, and it correctly explains why Statement 1 is true: the structural similarity between benzene and toluene leads to similar intermolecular forces.

5. **Conclusion:**
- Both statements are true, and Statement 2 provides the correct explanation for Statement 1.
- Therefore, the correct answer is Option A: Statement 1 is true, Statement 2 is true, and Statement 2 is the correct explanation for Statement 1.

### Final Answer:
**Option A: Statement 1 is true, Statement 2 is true, and Statement 2 is the correct explanation for Statement 1.**
