What can result from inadequate moisture control in environments where fungi grow?

Inadequate moisture control in environments conducive to fungi can lead to both increased allergens and pathogen growth, which is why the chosen answer encompasses both effects.

Fungi thrive in moist environments and can proliferate rapidly when moisture levels are not properly managed. As fungi grow, they release spores and other particulate matter into the air, which can act as allergens. These allergens can trigger allergic reactions and respiratory issues in sensitive individuals, thereby increasing health risks.

Simultaneously, the presence of fungi can also facilitate the growth of pathogens. Some fungi are capable of harboring and supporting the development of bacteria, viruses, and other harmful microorganisms. These pathogens can lead to more serious health complications, particularly for individuals with weakened immune systems or pre-existing health conditions.

Thus, the interplay of inadequate moisture control facilitates a dual impact in the environment, contributing to both allergen levels and pathogen proliferation, hence making the selection of an answer that includes both A and B as well-founded.
