Scientists hypothesize that disrupting our communities may increase our susceptibility to infectious diseases, predispose us to certain cancers, and contribute to conditions such as asthma and other allergies, irritable bowel syndrome, Crohn's disease, and autism.

A)microbial
B)exotoxin
C)protist
D)pathogen

The correct answer is option A) "microbial".

Explanation:

We live in a close relationship with our microbial communities, which live in many different regions of our body and constitute what is known as the human microbiota. Disrupting our microbial communities may increase our susceptibility to infectious diseases, as well as many other diseases, because we make room for others microorganisms to occupy their place. These microorganism most likely will not be beneficial to our body, on the contrary they act as pathogens.
