Answer:
B. The amount of lee that melted.
Explanation:
The dependent variable is more of what results from an action during an experiment. It is actually what is being tested for. In the experiment, the scientist seeks to understand the effect of salts on melting point of ice. He selects the different salts which can cause a ice to melt (independent variables) then he sets up to find out the effect of the salt on the ice.
He cannot control how much ice will melt. The properties of the salts would determine the extent and rate of the dissolution of the ice pack. This is the dependent variable which relies on the nature of the salt.
