D. Statement-1 is False, Statement-2 is True

Answer

To analyze the given statements regarding the Bohr model of the hydrogen atom, let's break down the solution step by step.

### Step 1: Understanding Statement 1
**Statement 1**: The Bohr model of the hydrogen atom does not explain the fine structure of spectral lines.

- The fine structure of spectral lines refers to the small splitting of spectral lines due to additional effects not accounted for in the basic Bohr model. This fine structure arises from relativistic effects and electron spin interactions.

### Step 2: Understanding Statement 2
**Statement 2**: The Bohr model does not take into account the spin of the electron.

- The Bohr model was developed before the concept of electron spin was introduced. Electron spin is a fundamental property of electrons that contributes to their magnetic moment and affects how they interact with magnetic fields. The omission of spin in the Bohr model is a significant limitation.

### Step 3: Analyzing the Relationship Between the Statements
- The lack of consideration for electron spin in the Bohr model leads to its inability to explain the fine structure of spectral lines. This means that Statement 2 provides a valid explanation for Statement 1.

### Step 4: Conclusion
- Both statements are true. Statement 1 is correct because the Bohr model does not explain fine structure, and Statement 2 is a correct explanation of why that is the case.

### Final Answer
Both Statement 1 and Statement 2 are true, and Statement 2 is the correct explanation for Statement 1.
