Final answer:
The First Amendment to the U.S. Constitution protects freedom of speech and freedom of religion. It doesn't cover the right to bear arms or the right to a fair trial, which are protected by the Second and Sixth Amendments, respectively.
Step-by-step explanation:
The First Amendment to the Constitution deals with several fundamental freedoms. Specifically, it addresses freedom of speech (a), freedom of religion (c), and by extension, the freedom of press, the right to peacefully assemble, and the right to petition the government for a redress of grievances. It does not address the right to bear arms (b), which is covered by the Second Amendment, nor the right to a fair trial (d), which is outlined in the Sixth Amendment.
