Concept:
The United Nations has adopted several core international human rights treaties over the decades to address the needs of specific groups and rights.
Step 1: Determining Adoption Years.
• C. International Covenant on Civil and Political Rights (ICCPR): Adopted in 1966 (along with the ICESCR).
• B. Convention on the Elimination of All Forms of Discrimination against Women (CEDAW): Adopted in 1979.
• A. Convention on the Rights of the Child (CRC): Adopted in 1989.
• D. Convention on the Rights of Persons with Disabilities (CRPD): Adopted in 2006.
Step 2: Applying the Sequence.
Sorting by year gives:
• C (1966) $\rightarrow$ B (1979) $\rightarrow$ A (1989) $\rightarrow$ D (2006).
Step 3: Conclusion.
The correct chronological order is C, B, A, D, which aligns with Option (3). This progression shows how international law first established broad civil rights before specializing in the protections for women, children, and finally, persons with disabilities.
