Answer 1

The baby most likely has cystic fibrosis. Cystic fibrosis is a genetic disorder caused by a mutation in a single gene (the CFTR gene), whereas the other options listed (arthritis, heart disease, and diabetes) can have multifactorial causes and are not typically classified as single-gene disorders.
