Choose the correct statement.

Options

A. C.V. Raman is associated will1 scattering of light by the molecules
B. Neil Bohr is associated with scattering of light by the molecules
C. S. Chandrashekhar is associated with scattering of light by the molecules
D. Heisenberg is associated with radioactivity

Answer

To solve the question of which statement is correct, we will evaluate each of the four statements provided in the options.

### Step 1: Analyze Option 1
- **Statement**: C.V. Raman is associated with scattering by the molecule.
- **Evaluation**: This statement is correct. C.V. Raman is known for his work on the scattering of light by molecules, which led to the discovery of the Raman Effect.

### Step 2: Analyze Option 2
- **Statement**: Niels Bohr is associated with scattering of light by the molecules.
- **Evaluation**: This statement is incorrect. Niels Bohr is primarily known for his contributions to the understanding of atomic structure and quantum theory, not for scattering of light.

### Step 3: Analyze Option 3
- **Statement**: (The statement is incomplete in the transcript but appears to be similar to Option 2).
- **Evaluation**: Assuming it is also incorrect based on the context, as it likely pertains to atomic structure or a similar concept rather than scattering.

### Step 4: Analyze Option 4
- **Statement**: Heisenberg is associated with radioactivity.
- **Evaluation**: This statement is incorrect. Werner Heisenberg is known for the uncertainty principle in quantum mechanics, not for radioactivity.

### Conclusion
After evaluating all the options, the only correct statement is Option 1: C.V. Raman is associated with scattering by the molecule.

### Final Answer
The correct statement is **Option 1**.
