Strong chlorosis is due to the deficiency of _____________ in plants?
Correct answer: B. Nitrogen
- A. Magnesium
- B. Nitrogen
- C. Potassium

Explanation
Nitrogen deficiency reduces chlorophyll formation, producing widespread or strong yellowing called chlorosis, especially in older leaves. Magnesium and iron deficiencies can also cause chlorosis, so students may choose magnesium because magnesium is part of chlorophyll or iron because iron is needed for chlorophyll formation.
