Amnesty International is

The correct option is "a global Human Rights Movement".

Explanation:
Amnesty International is a non-governmental organization (NGO) focused on human rights. Founded in London in 1961, the movement campaigns to protect human rights globally. It works to mobilize public opinion to put pressure on governments that tolerate abuse and violations of human rights, making it a global human rights movement rather than an agency of the United Nations, a medical emergency team, or a voluntary organization focused primarily on poverty alleviation.
