According to US Congress, how should Americans display the flag?

The correct choice is that Americans should display the flag with a special degree of respect. This reflects the guidelines established by the United States Congress, specifically in the Flag Code, which outlines proper flag etiquette. The code emphasizes that the American flag is a symbol of national pride and integrity and should be honored accordingly.

Displaying the flag with a special degree of respect means that it should be treated with care and dignity. This includes actions such as ensuring the flag is clean, properly maintained, and displayed in a manner that shows reverence. For instance, it should be raised briskly and lowered ceremoniously, and it shouldn’t touch the ground.

The other options lack the clarity and specificity that the chosen answer provides. For example, "full general respect" is too vague and does not capture the specific guidelines set forth for flag display. Similarly, "minimal public visibility" contradicts the intent of the flag's display, as it is meant to be visible and prominent as a national symbol. The phrase "without any restrictions" suggests a lack of etiquette, which is contrary to the established practices that guide how the flag should be treated with honor and care in various public and private settings.
