Which of the following statements is correct?

a- Human rights have come to be classified into three types.
b- The rights of colonized people or ethnic and indigenous minorities are considered a universal human right.

Only statement a is correct.

Human rights have come to be classified into three types. The first type is political rights such as freedom of speech and assembly. The second type is economic and social rights. The third type is the rights of colonised people or ethnic and indigenous minorities. While there is broad agreement on this classification, there is no agreement on which set of rights should be considered as universal human rights, nor what the international community should do when rights are being violated.
