Why are children more prone to croup when they acquire a viral infection than adults infected with the same virus? A) Children's immune systems are not as developed as those of adults, so they are more prone to infection. B) Adults were vaccinated against the virus that causes croup, whereas most children were not. C) A child's airway is narrower than an adult's, and even minor swelling can result in obstruction.
