Which of the following is correct statement ?

Options

A. Both facilitated transport and active sensitive to inhibitors
B. Both facilitated transport and simple diffusion requires ATP energy
C. Both facilitated transport and active transport selective
D. All of the above

Answer

To solve the question regarding which statement is correct about transport mechanisms in plants, we need to analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Types of Transport:**
- There are two main types of transport mechanisms: **Facilitated Transport** and **Active Transport**.
- **Facilitated Transport** (also known as facilitated diffusion) does not require energy (ATP) and occurs along the concentration gradient.
- **Active Transport** requires energy (ATP) to move substances against their concentration gradient.

2. **Evaluate the First Statement:**
- The first option states that "both facilitated transport and active transport are sensitive to inhibitors."
- This is true because both processes involve proteins (transport proteins in facilitated transport and pumps in active transport) that can be inhibited by certain substances.

3. **Evaluate the Second Statement:**
- The second option claims that "facilitated transport and simple diffusion require ATP."
- This statement is incorrect. Both facilitated transport and simple diffusion are passive processes and do not require ATP.

4. **Evaluate the Third Statement:**
- The third option states that "both facilitated transport and active transport are selective."
- This statement is correct. Both transport mechanisms exhibit selectivity, meaning they allow specific substances to pass through.

5. **Conclusion:**
- The correct statements are the first and third options. However, since the question asks for which of the following is correct, we can conclude that the first option is correct.

### Final Answer:
The correct statement is: **Both facilitated transport and active transport are sensitive to inhibitors.**
