A few mold spores land on the skin but do not survive due to the lack of moisture and the presence of oxygen. These spores have been prevented from harming the body by which type of barrier?

a. biologicalb. chemicalc. physicald. mechanical

C) physical

Explanation:

Mold spores are the reproductive structures produced by the fungus which can grow on the substratum if they get suitable conditions.

One of the favourable factors for the germination of the spores in the presence of the moist condition which has not been provided by the human body in the given condition. This prevents the growth of the mould spore and acts as the physical barrier as moisture is an abiotic physical factor which has prevented the growth of the fungus.

Thus, C) physical is the correct answer.
