What age group is the most susceptible to sepsis?
Infants.
Adolescents.

Young adults.
Elderly patients are at most risk for developing sepsis because of decreased physiologic reserves and an aging immune system.

Option A: Infants may have less physiologic reserves yet they have vaccines that strengthen their immune system than the elderly.
Option B: Adolescents may not have fully mature reserves yet they have a stronger immune system than the elderly.
Option D: Adolescents may not have fully mature reserves yet they have a stronger immune system than the elderly.
