Given below are two statements: one is labelled as

Assertion $\mathrm{A}$ and the other is labelled as Reason $\mathrm{R}$.

Assertion $\mathrm{A}$ : Finest gold is red in colour, as the size of the particles increases, it appears purple then blue and finally gold.

Assertion $\mathrm{R}$ : The colour of the colloidal solution depends on the wavelength of light scattered by the dispersed particles.

In the light of the above statements, choose the most appropriate answer from the options given below

Given below are two statements. One is labelled as Assertion $\mathrm{A}$ and the other is labelled as Reason $\mathrm{R}$.

Assertion $\mathrm{A}$ : Activated charcoal adsorbs ${\mathrm{SO}}_2$ more efficiently than ${\mathrm{CH}}_4$.

Reason $\mathrm{R}$ : Gases with lower critical temperatures are readily adsorbed by activated charcoal. In the light of the above statements, choose the correct answer from the options given below.

Given below are two statements: one is labelled as Assertion $\mathrm{A}$ and the other is labelled as Reason $\mathrm{R}$

Assertion $\mathrm{A}$ : Dissolved substances can be removed from a colloidal solution by diffusion through a parchment paper.

Reason $\mathrm{R}$ : Particles in a true solution cannot pass through parchment paper but the collodial particles can pass through the parchment paper.
