A. It shows that people love the United States.

Explanation:

Patriotism is the devotion and love for one's country. Most Americans will have an attachment to the United States, and they love their country and will fight for it. Patriotism is a defining factor of America's national identity for that reason. The Great Seal is a seal used on documents for authentication and have nothing to do with patriotism or America's national identity. If the question stated freedom instead of patriotism, I would have chose option C, but patriotism is not providing the same treatment for everyone, it's the attachment one has to their home country. Patriotism isn't just the feeling you get when entering the country, its deeper than that, and you have to form a bond with the country, not just enter it.
