which one is a `C_(4)`-plant ?

Options

A. papaya
B. pea
C. potato
D. Maize/corn

Explanation

To determine which one is a C4 plant, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Characteristics of C4 Plants**:
- C4 plants are adapted to dry tropical regions and can tolerate high temperatures.
- They have specialized mechanisms to minimize water loss through transpiration.
- They exhibit higher productivity and biomass production compared to C3 plants.
- C4 plants have a unique anatomy known as Kranz anatomy.

2. **Identify the Photosynthetic Pathways**:
- C4 plants utilize both the C4 cycle and the C3 cycle for sugar synthesis. This dual pathway allows them to efficiently fix carbon dioxide even under conditions that would typically favor photorespiration in C3 plants.

3. **Examine the Given Options**:
- Look at the options provided in the question to identify which plant is classified as a C4 plant. Common examples of C4 plants include maize (corn) and sugarcane.

4. **Select the Correct Answer**:
- Among the options, identify maize (corn) or sugarcane as the C4 plant. If these options are present, choose them as the correct answer.

5. **Conclude Your Answer**:
- Based on the characteristics and examples of C4 plants, conclude that maize (corn) is a C4 plant.

### Final Answer:
The correct answer is maize (corn), which is a C4 plant.
