Answer: Option (b) is the correct answer.

Explanation:

A substance that dissociates into ions upon dissolving in water is able to conduct electricity due to the movement of ions or electrons.

This is because conductivity is the ability of a substance through which electricity can flow due to the free movement of electrons.

For example, MgCl_{2} is an ionic compound and when it is dissolved in water then it readily dissociates into magnesium and chlorine ions.

Therefore, it is able to conduct electricity.

Whereas H_{2}O_{2}, CH_{3}OH, and NH_{3} are all non-polar in nature. Hence, they do not dissociate into ions.

So, they do not conduct electricity.

Thus, we can conclude that out of the given options MgCl_{2} best conducts electricity in a aqueous solution.

Usually, the more something ionizes, the better it conducts electricity. NH3 is molecular. CH3OH is an alcohol and doesn't ionize well. I'd say MgCl2 was more ionizable than H2O2, just because it's less likely to cause metathesis.

Yes it is available. It will continue catalyzing the reactions until it becomes completely consumed. That's how enzymes work. They work and are eventually consumed in the process completely without altering the reaction in any way other than speeding it up.
