The correct answer is B, as the right to petition members of the government is contained in the First Amendment.
This amendment prohibits Congress from enacting laws that do not allow citizens to petition the government for compensation of grievances: "Congress shall make no law ... prohibiting ... to petition the Government for a redress of grievances."
The right of petition guarantees the right to claim compensation from the government for violations of rights through litigation or other measure that the government may order. Together with the right of assembly, it allows people to meet in order to obtain changes in government.
