Answer:

D. the agar concentration is low to allow movement to motile bacteria

Explanation:

Motility test medium is a culture medium that seeks to promote the differentiation of microorganisms based on the way they move. For the microorganisms to be able to move around in the culture medium, it is necessary that the agar used has a low concentration, leaving the culture medium semi-solid and not solid. In addition, this medium needs to be autoclaved, does not use colored agar and should not be kept in the refrigerator to prevent it from solidifying.
