Options

A. A–1 , B – 2 , C – 3 , D – 4 , E – 5
B. A–3 , B – 5 , C – 1 , D – 2 , E – 4
C. A–3 , B – 2 , C – 5 , D – 4 , E – 1
D. A–5 , B – 3 , C – 4 , D – 2 , E – 1

Answer

To solve the matching question, we need to pair the items from column A with the correct items from column B based on their definitions and functions. Here’s the step-by-step solution:

### Step 1: Analyze Item A - Carboxylation
- **Carboxylation** is a process that involves the fixation of carbon dioxide into organic compounds. The enzyme responsible for this process is **Rubisco**.
- **Match:** A (Carboxylation) → 3 (Rubisco)

### Step 2: Analyze Item B - Phosphorylation
- **Phosphorylation** refers to the addition of a phosphate group to a molecule, which is crucial in the production of **ATP** (adenosine triphosphate).
- **Match:** B (Phosphorylation) → 5 (ATP)

### Step 3: Analyze Item C - Photolysis of Water
- **Photolysis of water** is the process where water is split into hydrogen and oxygen in the presence of light, resulting in the **evolution of oxygen**.
- **Match:** C (Photolysis of water) → 1 (Oxygen evolution)

### Step 4: Analyze Item D - Phosphoglycolate
- **Phosphoglycolate** is a product formed during **photorespiration**, a process that occurs when oxygen is consumed and carbon dioxide is released in plants.
- **Match:** D (Phosphoglycolate) → 2 (Photorepiration)

### Step 5: Analyze Item E - Nitrosomonas
- **Nitrosomonas** is a genus of bacteria that performs **chemosynthesis**, utilizing inorganic compounds to produce organic matter.
- **Match:** E (Nitrosomonas) → 4 (Chemosynthesis)

### Final Matching Summary:
- A → 3 (Carboxylation → Rubisco)
- B → 5 (Phosphorylation → ATP)
- C → 1 (Photolysis of water → Oxygen evolution)
- D → 2 (Phosphoglycolate → Photorepiration)
- E → 4 (Nitrosomonas → Chemosynthesis)

### Conclusion:
The correct combination is:
- A - 3
- B - 5
- C - 1
- D - 2
- E - 4

### Answer:
The correct option is **2**.
