Options

B. Young, yellow
C. young, orange
D. old , brown spotted.

Answer

**Step-by-Step Solution:**

1. **Understanding Iron Deficiency**: Iron (Fe) is an essential micronutrient for plants, playing a crucial role in various physiological processes, including chlorophyll synthesis and electron transport in photosynthesis.

2. **Identifying Affected Leaves**: In the case of iron deficiency, it primarily affects young leaves rather than older ones. This is because iron is not mobile within the plant; thus, it cannot be easily transported from older leaves to younger ones.

3. **Symptoms of Iron Deficiency**: The most common symptom of iron deficiency is chlorosis, which is the yellowing of leaves. This yellowing occurs due to a lack of chlorophyll, the pigment responsible for the green color in plants.

4. **Finalizing the Answer**: Based on the above points, the correct completion of the statement is: "Fe deficiency causes **young** leaves to turn **yellow**."

**Final Answer**: Fe deficiency causes **young** leaves to turn **yellow**.
