Explanation:

The patient's symptoms (recurrent pulmonary infections, steatorrhea, failure to thrive) suggest Cystic Fibrosis (CF). The gold - standard test for CF is the sweat chloride test. Serum beta - lipoprotein is related to abetalipoproteinemia (different symptoms), serum phenylalanine to phenylketonuria (different symptoms), and serum ceruloplasmin to Wilson's disease (different symptoms). So measuring sweat chloride is the most appropriate.

B. Sweat Chloride
