The best electrical conductor is:

a. 0.10 M NH₃

b. 0.10 M NaCl

c. 0.10 M HC₂H₃O₂ (acetic acid)

d. 0.10 M C₂H₅OH (ethanol)

B

Explanation:

Solutions of substances that can conduct electricity are termed electrolytes. These solutions allow electricity to pass through them.

How strong a solution is to allow the passage of electricity is strongly dependent upon the availability of charge carriers within the solution matrix. In sharp contrast to the other solutions in the question, we can see that the presence of sodium and chloride ions in the matrix provides a boost for the solution to act properly as an electrolyte. Hence, it is a better solution than the rest of the options to serve as an electrical conductor
