QuestionChoice
Incorrect - This patient is presenting with osteomalacia, which involves a softening of the bones and hence susceptibility to recurrent fractures. Vitamin C deficiency is the main risk factor for the development of scurvy. Individuals with scurvy will suffer from fatigue, irritability, severe joint and leg pain, swollen and bleeding gums, and will bruise easily. It is not implicated in the development of osteomalacia.

Which of the following vitamins is most likely to be deficient?
