Elimination of exploitation is a principle mentioned in:

Article 3 of the Constitution is a foundational principle that explicitly states the State shall ensure the elimination of all forms of exploitation. This article aims to establish social and economic justice by preventing any individual or group from exploiting another.

• Option B (3) is correct because it directly addresses the constitutional provision for the elimination of exploitation.
• Option A (2A) refers to the Objectives Resolution, which is part of the Constitution but does not specifically detail the elimination of exploitation.
• Option C (4) guarantees the right of individuals to be dealt with in accordance with law.
• Option D (6) defines High Treason.

Therefore, Article 3 is the precise constitutional reference for this principle.
