Vedclass · Answer

(C) Asthma is a chronic respiratory condition often triggered by allergens like dust,pollen,or smoke. Exposure to these triggers can lead to inflammation and narrowing of the airways,making breathing difficult. Therefore,patients are advised to avoid such triggers. The Reason statement is incorrect because an allergic response typically causes vasodilation (widening of blood vessels) and increased capillary permeability,not vasoconstriction. This vasodilation can lead to a sudden drop in blood pressure,potentially resulting in anaphylactic shock and death. Thus,the Assertion is correct,but the Reason is incorrect.

$A$: Asthma patients must never be exposed to dust. $R$: Allergic response may cause vasoconstriction and death.
