Answer

To solve the question of matching the types of respiration with their respective sites in bacteria, cyanobacteria, and eukaryotic cells, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Respiration in Bacteria:**
- In bacteria, respiration occurs primarily in the **mesosomes**. These are folded structures in the plasma membrane that facilitate respiration and ATP production.
- **Match:** (a) Respiration in bacteria → (f) Mesosomes.

2. **Identify Respiration in Cyanobacteria:**
- Cyanobacteria, which are capable of photosynthesis, perform respiration at the **cytoplasmic membrane** (also known as the plasma membrane). They do not have mesosomes.
- **Match:** (b) Respiration in cyanobacteria → (e) Cytoplasmic membrane.

3. **Identify Respiration in Eukaryotic Cells:**
- In eukaryotic cells, respiration occurs in the **mitochondria**, which are known as the powerhouse of the cell. This is where aerobic respiration takes place, producing ATP through complex biochemical pathways.
- **Match:** (c) Respiration in eukaryotic cells → (d) Mitochondria.

### Final Matching:
- (a) Respiration in bacteria → (f) Mesosomes
- (b) Respiration in cyanobacteria → (e) Cytoplasmic membrane
- (c) Respiration in eukaryotic cells → (d) Mitochondria

### Correct Combination:
The correct combination is:
- A, F
- B, E
- C, D
