**Assertion: When a beam of light is passed through a colloidal solution placed in a dark place, the path of the beam becomes visible.**

**Reason: Light gets scattered by the colloidal particles.**

The correct answer is option 'A', which states that both the assertion and the reason are true, and the reason is the correct explanation of the assertion.

Explanation:

When a beam of light is passed through a colloidal solution placed in a dark place, the path of the beam becomes visible. This phenomenon can be explained by the scattering of light by the colloidal particles present in the solution.

**Scattering of Light:**

When a beam of light passes through a medium, it interacts with the particles present in the medium. The interaction can cause the light to change its direction. This phenomenon is known as scattering of light.

**Colloidal Solutions:**

Colloidal solutions are mixtures in which tiny particles of one substance are uniformly dispersed in another substance. These particles are larger than individual molecules but smaller than visible particles.

**Light Scattering in Colloidal Solutions:**

When a beam of light passes through a colloidal solution, the light interacts with the colloidal particles present in the solution. The particles scatter the light in different directions, causing it to become visible.

**Explanation of Assertion and Reason:**

The assertion states that when a beam of light is passed through a colloidal solution placed in a dark place, the path of the beam becomes visible. This is true because the scattered light rays become visible, revealing the path of the beam.

The reason states that light gets scattered by the colloidal particles. This is also true because when light interacts with the colloidal particles present in the solution, it gets scattered in different directions.

Therefore, both the assertion and the reason are true, and the reason provides the correct explanation for the assertion. The colloidal particles in the solution cause the scattering of light, making the path of the beam visible in a dark place.

In conclusion, the path of a beam of light becomes visible when passed through a colloidal solution in a dark place due to the scattering of light by the colloidal particles.
