The answer is 2) Dependent variables.

Explanation:

In experimental studies, an independent variable is predicted to affect a dependent variable. Jasmeet's experiment is lacking a dependent variable because we don't know what change is expected to occur after the fish have been fed.

A possible dependent variable could be, for example, the fish performance in a fight. Then, we could say the performance depends on the amount of food given.
