Step 1: Understanding the Concept:
This question tests the knowledge of important international observance days designated by the United Nations, which are related to various human rights issues.
Step 2: Detailed Explanation:
Let's match each day in LIST-I with its correct date in LIST-II.
A. International Day Against Child Labour: This is observed annually on 12th June. The date in the question (15th June) appears to be a typo, as 12th June is the correct date. Assuming 'I' represents the correct date's month, this is the intended match.
B. International Day for Older Persons: This day is celebrated every year on 1st October. This matches with II.
C. International Day for the Elimination of Racial Discrimination: This is observed on 21st March. This matches with IV.
D. International Human Rights Day: This is one of the most well-known international days, celebrated on 10th December, the anniversary of the adoption of the Universal Declaration of Human Rights in 1948. This matches with III.
Step 3: Final Answer:
Based on the correct dates, the matching is:
A → I (June)
B → II (1st October)
C → IV (21st March)
D → III (10th December)
This corresponds to the sequence A-I, B-II, C-IV, D-III.
