The correct answer is B) the mayor’s office from displaying a cross.
The Establishment clause would prevent the mayor’s office from displaying a cross.
Religion is a delicate issue in the United States, and although every citizen is free to practice its own religious thoughts, religion in government has restrictions. We are referring to the First Amendment's Establishment Clause that does not allow the government to support any law to establish a preferent religion over the other. This clause also prohibits any action on the part of the government to favor the practice of a specific type of religion. That is why the Mayor's office cannot display a cross
