Xerophthalmia is a condition that is characterized by conjunctiva and cornea dryness. It is caused due to deficiency in vitamin A.
Bone softening is termed as osteomalacia and it is caused due to low levels of calcium, vitamin D and phosphate or due to calcium resorption.
Anemia is a medical condition that is characterized by low levels of hemoglobin. It can be due to deficiency of iron, vitamin B12.
Pellagra is caused due to deficiency of nicotinic acid, also known as niacin or vitamin B3. The disease is characterized by symptoms like dermatitis, diarrhoea, and dementia.
So, the correct option is option A, pellagra.
