Mr XY was found to be anaemic. During history taking, he informed his doctor that he was a strict vegetarian who did not consume any meat, fish or milk products.

Correct Answer: B

Rationale: A strict vegetarian avoiding meat, fish, and milk products lacks dietary vitamin B12 (found in animal products), leading to B12 deficiency anemia (B). Iron deficiency (A) is possible but less likely with plant-based iron sources, erythropoietin defects (C) are renal-related, calcium deficiency (D) doesn’t cause anemia, and transferrin production defects (E) are rare—B12 deficiency fits the history.

Correct Answer: C

Rationale: The testicle is a mixed gland because it has both endocrine functions (secreting testosterone into the bloodstream) and exocrine functions (producing sperm, which is released via ducts). Option A is incorrect as gametes are exocrine products, not endocrine. Option B reverses the definitions, and D is too narrow, as it omits the exocrine role.
