Step 1: Prospective screening is screening carried out for the benefit of others or for disease control, on a specific request from an authority, where the main purpose is case detection rather than the direct benefit of the person screened.
Step 2: Screening of immigrants entering a country is the classic example: it is done at the authority's request, mainly to detect and control communicable disease in the community, not primarily for the immigrant's own health. So immigrant screening is the answer.
Step 3: The other options are forms of screening done for the individual's own benefit: neonatal thyroid screening, Pap smear for cervical cancer, and diabetes screening are all early-detection programmes aimed at the person screened.
