Explanation:

In an experiment, the independent variable is the factor that is changed or manipulated. Here, the scientist used three different types of cheese. The type of cheese is what is being varied to observe its effect (on bacteria content). The amount of bacteria is the dependent variable (what is measured as a result of the change in the independent variable). The number of types of cheese is just a count related to the independent variable but not the variable itself. And the type of bacteria is not mentioned as being changed in this context.

Answer:

the type of cheese
