The correct answer is: It's linked to ailments like sinus infections and asthma.

The correct answer is B. Mould is linked to ailments like sinus infections and asthma. This is an accurate statement because mould can release spores into the air that, when inhaled, can cause respiratory issues in individuals. Sinus infections and asthma are among the health problems associated with exposure to mould. It is important to address mould problems promptly to mitigate health risks for occupants of the property. Options A, C, D, E, and F are incorrect: Option A is incorrect because mould thrives in damp or moist conditions, rather than drier areas. Option C is incorrect because while keeping heating ducts clean is important for indoor air quality, it does not render mould non-problematic. Option D is incorrect because mould can penetrate beyond the surface of walls, making it impossible to eradicate simply through cleaning the walls. Option E is incorrect as mould removal typically requires specialized chemicals and processes to effectively eliminate the issue. Option F is incorrect because well-ventilated structures are not immune to mould issues if moisture levels are not properly controlled.
