The correct answer is:

A.
The dependent variable is the cost, and the independent variable is the area of the floors.

Explanation:
1. In this scenario, the cost of the wood flooring depends on the area of the floors that Chris wants to cover. The cost varies based on how much flooring material is needed to cover a specific area.
2. The independent variable is the factor that is controlled or changed in an experiment or situation. In this case, Chris has control over the area of the floors he wants to cover, which makes it the independent variable.
3. The dependent variable, on the other hand, is the factor that is being measured and is influenced by the independent variable. The cost of the wood flooring is dependent on the area of the floors since the cost changes as the area to be covered changes.

Therefore, in this situation, the cost (dependent variable) is dependent on the area of the floors (independent variable) that Chris wants to cover with new wood flooring.
