Answer:
B)The first and second beakers contain a solution that completely dissociates the ions. These ions create an electrical current. The third beaker solution does not dissociate ions. It is a nonelectrolyte.
Step-by-step explanation:
Electrolytes dissociate ions. They are also conductors. Since the first 2 bulbs light up strongly, we can assume that the ions completely dissociated. Since the 3rd did not light up, it is a nonelectrolyte.
