Final answer:
The right concerned with the buying and selling of human beings is C. right against exploitation, which prevents the treatment of individuals as chattel and ensures their basic human dignity
Step-by-step explanation:
The right concerned with the buying and selling of human beings is C. right against exploitation. This right directly addresses practices such as slavery and human trafficking, prohibiting any form of selling or trading humans as if they were commodities. It seeks to protect individuals from being treated as property and ensures their fundamental human dignity. The practice of buying and selling human beings violates this essential right and is considered a severe form of exploitation.
Economic rights, civil liberties, and the historical context of human rights are also crucial to understanding the broader scope of the rights against exploitation. Economic rights include the ability of individuals to buy and sell property freely, but this does not extend to the trading of humans itself. Civil liberties, such as freedom of movement, may also relate to discussions around exploitation when limitations are imposed that inhibit personal freedoms unjustly.
