This question asks to arrange four significant international human rights events in chronological order based on their adoption dates. Let's identify the dates for each event to establish the correct sequence.

Understanding the Key Human Rights Events

We need to determine the year each of the following events occurred:

• A. Declaration on Torture: This refers to the Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment, which was adopted by the United Nations General Assembly on December 10, 1984.
• B. Convention on the Rights of the Child: This landmark convention was adopted by the United Nations General Assembly on November 20, 1989.
• C. Genocide Convention: Officially known as the Convention on the Prevention and Punishment of the Crime of Genocide, it was adopted by the United Nations General Assembly on December 9, 1948.
• D. Universal Declaration of Human Rights (UDHR): This foundational document was adopted by the United Nations General Assembly on December 10, 1948.

Determining the Chronological Order

Now, let's place these events in order from earliest to latest:

1. 1948: Both the Universal Declaration of Human Rights (D) and the Genocide Convention (C) were adopted in 1948. The UDHR is often considered the foundational document for modern human rights, setting a common standard for all peoples and nations, and is generally listed first in such contexts.
2. 1984: The Convention Against Torture (A) was adopted.
3. 1989: The Convention on the Rights of the Child (B) was adopted.

Therefore, the chronological order is D, C, A, B.

Matching the Chronological Order to the Options

Comparing our derived order (D, C, A, B) with the given options:

• Option 1: A, B, C, D
• Option 2: C, D, A, B
• Option 3: D, C, A, B
• Option 4: C, D, B, A

The sequence D, C, A, B correctly matches Option 3.
