Which one of the following statements best expresses the way in which the International Covenant on Civil and Political Rights (ICCPR) helps to secure human rights under the auspices of the UN?

B.
The ICCPR is a list of obligations accepted by signatory states, but there is no effective enforcement procedure available because it relies entirely on states reporting to the Human Rights Committee on their own behaviour.
C.
The ICCPR is a list of obligations accepted by signatory states; it is enforced through the reporting process of the UN Human Rights Committee and there is also an Optional Protocol by which states can grant their citizens a right of complaint.
D.
The ICCPR is a list of obligations accepted by signatory states, but there is no effective enforcement procedure available; in particular, there is no process for individuals to bring complaints against the behaviour of their own states.
