Correct Answer: Option A — Both Statement I and Statement II are true
Analysis of the Statements
Statement I is true: The thymus is a primary lymphoid organ consisting of two lobes. It is situated in the upper front part of the chest (the mediastinum), specifically behind the sternum (breastbone) and in front of the heart.

Statement II is true: The primary function of the thymus is the production and "training" of T-lymphocytes (T-cells). It creates a specialized environment where immature lymphocytes (thymocytes) from the bone marrow differentiate into mature, functional T-cells that can distinguish between "self" and "non-self" pathogens.
