C. a - (iii) , b - (ii) , c - (i)
D. a - (i) , b - (ii) , c - (ii)

Answer

To solve the question of matching the mode of dark reactions with their correct examples, we need to analyze the given options and identify the correct associations.

### Step-by-Step Solution:

1. **Identify the Modes of Dark Reactions**:
- **Calvin Cycle**: This is also known as the C3 pathway, where the first stable product of CO2 fixation is a 3-carbon compound (3-phosphoglycerate, PGA).
- **C4 Plants**: In these plants, the first stable product of CO2 fixation is a 4-carbon compound (oxaloacetate).
- **CAM Plants**: These plants utilize Crassulacean Acid Metabolism, where CO2 is fixed at night and stored as organic acids, which are then converted back to CO2 during the day for the Calvin Cycle.

2. **Identify the Examples**:
- **Kalanchoe**: A known CAM plant.
- **Zea mays**: Commonly known as corn, this is a C4 plant.
- **Triticum**: This is wheat, which is a C3 plant.

3. **Match the Modes with Examples**:
- **Calvin Cycle (C3)**: Matches with **Triticum** (iii).
- **C4 Plants**: Matches with **Zea mays** (ii).
- **CAM Plants**: Matches with **Kalanchoe** (i).

4. **Final Matching**:
- (a) Calvin Cycle → (iii) Triticum
- (b) C4 Plants → (ii) Zea mays
- (c) CAM Plants → (i) Kalanchoe

### Final Answer:
- (a, iii), (b, ii), (c, i)
