From the following options, select the plant which is not an example for `C_4` plant.

Options

A. Sugercane
B. Rice
C. Maize
D. Shorghum

Answer

To solve the question of which plant is not an example of a C4 plant, we can follow these steps:

### Step 1: Understand C4 Plants
C4 plants are a type of plant that have a specific photosynthetic pathway. In these plants, carbon dioxide fixation occurs in two different types of cells: mesophyll cells and bundle sheath cells. The bundle sheath cells in C4 plants contain chloroplasts.

### Step 2: Identify Examples of C4 Plants
Common examples of C4 plants include:
- Sugarcane
- Maize (corn)
- Sorghum

### Step 3: Identify Examples of C3 Plants
In contrast, C3 plants do not have chloroplasts in their bundle sheath cells. Some examples of C3 plants include:
- Soybean
- Cowpea
- Rice

### Step 4: Analyze the Options
Now, let's analyze the options given in the question:
- Option A: Sugarcane (C4 plant)
- Option B: Rice (C3 plant)
- Option C: Maize (C4 plant)
- Option D: Sorghum (C4 plant)

### Step 5: Select the Correct Answer
From the analysis, we see that Rice (Option B) is the only plant listed that is not a C4 plant; it is a C3 plant. Therefore, the correct answer is:

**Option B: Rice**
