Which protection guaranteed by the bill of rights allows the students to protest

Free expression of one's beliefs is protected by the First Amendment to the U.S. Constitution, which generally protects free speech, freedom of religion, freedom of the press, and freedom of assembly.

Explanation:

the third answer is correct (c).

the laws that regulate the financing of political campaigns seek to guarantee the smoothness of funding so that there is no abuse of electoral economic power and to avoid the capture of future politicians by the donors.

this is because donor agents have their private interests that are not necessarily the same interests of the society that elected politicians must defend.

thus, interest groups should seek their interests within the legality of lobbying practices that are regulated.
