- AIncreases.
- BDecreases.
- CRemain unchanged.
- DNone of the above.
Explanation:
The conductivity of a weak electrolyte increases with an increase dilution. As the dilution increases the number of ion increases and they get free from their co-ions and can move independently from each other. So by increasing dilution the rate of conductivity increases as more ions are available for conductance.

Give the answer of quetion ($1$) and ($2$)

Statement $I$ : Bromination of phenol in solvent with low polarity such as $\mathrm{CHCl}_3$ or $\mathrm{CS}_2$ requires Lewis acid catalyst.
Statement $II$ : The lewis acid catalyst polarises the bromine to generate $\mathrm{Br}^{+}$.
In the light of the above statements, choose the correct answer from the options given below :
