A nurse working in a pediatrician's office is preparing to do a throat culture for a 5-year-old. The child's parent asks, "Why do we have to do this?" The best statement the nurse could make to the child's parent is:

A) "It is important to identify and treat a Streptococcus infection quickly to prevent major illness."
B) "We need to test every sick child for whooping cough."
C) "Doctors have really cut down on how many antibiotics are given because the insurance companies won't pay for them."
D) "Throat cultures are primarily used to test children for the mumps."
