Spherocytosis is a common cause of inherited haemolytic anaemia. The most likely cause for spherocytosis is

Correct Answer: B

Integral protein defects (A) are less specific, rolealux (C) is a typo (likely ‘rouleaux,’ unrelated), sickle cells (D) are sickle cell disease, and decreased RBC size (E) isn’t causative—peripheral protein defects are key.
