Explanation:

PKU (Phenylketonuria) screening in the US and Canada is done via mandatory newborn screening (testing at birth). Starting all babies on a PKU - free diet without testing is inappropriate. Testing moms during pregnancy or in - utero testing isn't the standard screening method for PKU in infants in these countries; newborn screening at birth is the established practice.

Answer:

A. By mandatory testing for PKU at birth.
