Final answer:
In the United States, discrimination on the basis of religion is generally prohibited by law, but religious organizations may have certain exemptions.
Step-by-step explanation:
In the United States, discrimination on the basis of religion is generally prohibited by law. However, there are some exceptions to this rule. For example, religious organizations such as St. Mary's Catholic Academy for Girls may be allowed to discriminate on the basis of religion as part of their religious freedom. This is because they have a specific religious mission and purpose.
On the other hand, municipal police departments, Sadie's Kosher Frozen Cuisine, and airlines with international routes would generally not be allowed to discriminate on the basis of religion as they are considered public accommodations or businesses that are open to the public.
