Explanation:
Free electrons are the main current carrier in the all materials .If the materials is having free electrons in their structure then they will allow to move the electrons from one place to another place .The current can be define as ,the charge per unit second .
In the given options only NaCl solution is having free electrons that is why only NaCl solution will conduct electricity.Solid NaCl , Solid sugar and Sugar solution do not have free electron in their structure that is why will not conduct electricity.
Therefore the answer will be b.
b. NaCl solution
