Most readily mobilized elements in plants is/are

Options

A. Potassium, bromine and carbon
B. Potassium,bromine and carbon
C. Potassium , sulphur, nitrogen and phosphorus
D. Boron, molybdenum and calcium

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the most readily mobilized elements in plants. Mobilized elements are those that can be transported easily within the plant.

2. **Identifying the Options**: The options provided are:
- A) Potassium, Bromine, Carbon
- B) Potassium, Bromine, Carbon
- C) Potassium, Sulfur, Nitrogen, Phosphorus
- D) Boron, Molybdenum, Calcium

3. **Defining Mobile and Immobile Elements**: In plants, elements are categorized as mobile or immobile. Mobile elements can be transported from older tissues to newer tissues, while immobile elements cannot be easily moved.

4. **Analyzing Each Option**:
- **Option A and B**: Both contain Carbon, which is a structural component of plants and is not readily mobilized. Therefore, these options can be eliminated.
- **Option C**: Contains Potassium, Sulfur, Nitrogen, and Phosphorus. All of these elements are known to be mobile in plants.
- **Option D**: Contains Boron, Molybdenum, and Calcium. These elements are generally considered less mobile compared to Potassium, Sulfur, and Phosphorus.

5. **Conclusion**: The most readily mobilized elements in plants are found in Option C: Potassium, Sulfur, Nitrogen, and Phosphorus. Therefore, the correct answer is C.
