Select incorrect statement

Options

A. Sulphur deficiency causes chlorosis of younger leaves, stunted growth and anthocyanin accumulation.
B. Magnesium deficiency may cause premature leaf abscission.
C. The chlorosis of leaves is a typical symptom of iron deficiency.
D. The symptoms of Molybdenum deficiency include Rosette like appearance and Khaira disease of rice

Explanation

To solve the question "Select incorrect statement," we will analyze each statement provided and determine which one is incorrect.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- **Statement:** "Sulphur deficiency causes the chlorosis of younger leaves, stunt growth and anthocyanin accumulation."
- **Analysis:** Sulphur is indeed essential for plants, and its deficiency leads to chlorosis (yellowing of leaves), stunted growth, and anthocyanin accumulation (which can cause red coloration in leaves).
- **Conclusion:** This statement is **correct**.

2. **Analyze the Second Statement:**
- **Statement:** "Magnesium deficiency may cause premature leaf abscission."
- **Analysis:** Magnesium is a crucial component of chlorophyll. A deficiency can lead to reduced chlorophyll production, which may result in premature leaf drop (abscission).
- **Conclusion:** This statement is **correct**.

3. **Analyze the Third Statement:**
- **Statement:** "Chlorosis of leaf is a typical symptom of iron deficiency."
- **Analysis:** Iron deficiency is well-known to cause chlorosis, especially in younger leaves, due to its role in chlorophyll synthesis.
- **Conclusion:** This statement is **correct**.

4. **Analyze the Fourth Statement:**
- **Statement:** "The symptoms of the molybdenum deficiency include the rosette-like appearance and chiral disease of rice."
- **Analysis:** The rosette-like appearance and chiral disease (or "chara disease") are actually associated with zinc deficiency, not molybdenum deficiency. Molybdenum deficiency can cause other symptoms, but not these specific ones.
- **Conclusion:** This statement is **incorrect**.

### Final Answer:
The incorrect statement is the fourth one: "The symptoms of the molybdenum deficiency include the rosette-like appearance and chiral disease of rice."
