A. The Fabric

Step-by-step explanation:

By definition and experimental unit is the entity which is subjected to different types of treatments during the experiment.

Here the fabric has been stained with different types of stains and and then have been treated with baking soda and bleach under different temperature environments. In the experiment each time the fabric has been given different treatment than the previous one. That's why the fabric is experimental unit in the experiment mentioned in the question.
