الإجابة: A. Folate
A macrocytic anaemia in an elderly woman living on a 'tea and toast' diet is the classic picture of folate deficiency: folate comes from leafy greens and body stores last only weeks, so poor intake shows quickly, and there are no symptoms beyond the anaemia. Vitamin B12 is the tempting alternative, but B12 stores last years, deficiency is usually from malabsorption (pernicious anaemia) or veganism, and it would typically bring neurological signs. Iron deficiency is microcytic; vitamins C and K do not cause macrocytosis.
