Number of the `alpha`- particle deflected in Rutherford's `alpha` -scattering experiment varies with the angle of deflection. Then the graph between the two is best represented by.

Options

A.
B.
C.
D.

Explanation

To solve the problem regarding the relationship between the number of alpha particles deflected in Rutherford's alpha-scattering experiment and the angle of deflection, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Alpha Scattering**:
- In Rutherford's experiment, alpha particles are directed towards a thin gold foil. Most of the alpha particles pass through the foil without any deflection, while a small fraction are deflected at various angles.

2. **Deflection Angles**:
