Stats Case Control Study Design Question

You have decided to confirm or refute the recent claims by medical journals that exclusive breast feeding for the first six months of life my protect against the development of atopy in children. You already have several children coming to the hospital with history of atopy and lack of breast feeding.
What control group would you choose to design your study?

a- children with atopy and who were breast fed in their infancy.
b- children without atopy and who were breast fed in their infancy.
c- children without atopy and visiting the outpatient clinic for routine physicals.
d- children with atopy and who were breast fed for three months only.
e- children without atopy and who were not breast fed in their infancy.
