Vedclass · Answer

(A) The assertion $(S)$ is true because children in developed cities are exposed to a more sanitized environment,which reduces their exposure to antigens early in life,leading to higher rates of allergies.The reason $(R)$ is also true because modern lifestyles,characterized by excessive hygiene and reduced exposure to natural environments,lead to a lower development of the immune system,making individuals more susceptible to hypersensitivity reactions (allergies).Therefore,$R$ correctly explains $S$.

$R -$ Reason: Modern lifestyle leads to a decrease in immunity.
