Answer :
Pledge of Allegiance contains the phrase "under God" and as such the obligation to participate in the Pledge clashes with the freedom of religion. Freedom of religion is written into law in the First Amendment, adopted in 1791.
The student may invoke the first amendment to the United States Constitution, which is part of the United States Bill of Rights.
