Answer:
Option B, diabetes
Step-by-step explanation:
Diabetes mellitus (DM) is characterized by a lack of insulin in order to properly regulate the glucose circulating within the bloodstream either due to an autoimmune condition (Type 1, T1) or a developed resistance as a result of lifestyle (Type 2, T2). Exposure to air pollution may magnify health problems of Type 2 diabetes indirectly, as with more air pollution may come a lower likelihood of performing regular aerobic exercises outdoors that could help with preventing T2DM. However, this would not magnify the autoimmune diabetes of T1DM.
Exposure to air pollution is, however, known to have negative cardiovascular effects and respiratory system, such as triggering acute coronary syndrome according to the American Heart Association, which could blood supply to the heart muscle is occluded which then can lead to myocardial infarction, or heart attack. Inhaling toxic substances and particulate matter can cause a plethora of bronchial issues (e.g. bronchitis, asthma exacerbation, bronchoconstriction) which compromise the body's ability to adequately perfuse oxygen. Therefore, air pollution could also magnify health problems like strokes, which occur when the brain's oxygen supply is insufficient for the needs of its tissues.
