Correct Answer: Option B
Explanation

Iron deficiency in plants leads to chlorosis, which is the yellowing of leaves. Chlorosis occurs because iron is necessary for the formation of chlorophyll, which is the green pigment in plants that absorbs light energy for use in photosynthesis. Without sufficient iron, the plant cannot produce enough chlorophyll, leading to yellow leaves. Stunted growth is also a symptom of iron deficiency as iron is essential for various metabolic processes including DNA synthesis.
