Concept:
The United Nations Security Council (UNSC) is one of the principal organs of the UN responsible for maintaining international peace and security. It consists of permanent and non-permanent members.
Step 1: Understand composition.
The UNSC has:
• 5 permanent members (P5)
• 10 non-permanent members elected by the General Assembly
Step 2: Examine term duration.
Non-permanent members are elected for a fixed term of:
Two years
They are elected by a two-thirds majority of the UN General Assembly.
Step 3: Understand rotation system.
Every year:
• 5 non-permanent members are replaced
• 5 continue for the second year of their term
This ensures continuity in the Council’s functioning.
Step 4: Eliminate options.
• One year is too short for UNSC representation.
• Three and four years are not provided under the UN Charter.
Conclusion:
Non-permanent members serve a term of two years. Hence, Option (B) is correct.
