Dietary deficiencies are disorders which occur because of a lack of essential nutrients in the diet or because the body cannot absorb and process those nutrients once they are eaten. Most dietary deficiency diseases are caused by a lack of protein, vitamins, or minerals. Iron is necessary for the formation of certain proteins and enzymes. Haemoglobin, which is the oxygen-carrying protein in the blood, is iron-dependent protein. Iron deficiency can lead to anaemia, a lack of oxygen in the blood, which in turn can lead to fatigue and other complications. Good food sources of iron are liver, lean meats, legumes, dried fruits, and green leafy vegetables. 
Therefore, the correct answer is option A.
