Answer

To solve the question of matching Column I with Column II, we will analyze each item in Column I and find its corresponding match in Column II.

### Step-by-Step Solution:

1. **Trachea**:
- The trachea is a cartilaginous tube that connects the larynx to the bronchi of the lungs. It consists of cartilaginous rings that support its structure.
- **Match**: (A) Trachea → (iii) Cartilaginous rings

2. **Respiratory Centre**:
- The respiratory center is located in the medulla oblongata of the brain, which controls the rhythm of breathing.
- **Match**: (B) Respiratory centre → (iv) Medulla oblongata

3. **Yeast**:
- Yeast undergoes anaerobic respiration to produce ethanol and carbon dioxide.
- **Match**: (C) Yeast → (vii) Ethanol

4. **Insects**:
- Insects breathe through a system of tubes called tracheae, which is known as tracheal respiration.
- **Match**: (D) Insects → (vi) Tracheal respiration

5. **Fish**:
- Fish breathe through gills, which is referred to as branchial respiration.
- **Match**: (E) Fish → (vii) Branchial respiration

6. **Biologically Useful Energy**:
- The energy produced during cellular respiration is in the form of ATP, which is biologically useful.
- **Match**: (F) Biologically useful energy → (ii) ATP

7. **100 mm Hg**:
- This value refers to the partial pressure of oxygen (PO2) in alveolar air, which is approximately 104 mm Hg.
- **Match**: (G) 100 mm Hg → (i) PO2 in alveolar air

8. **Vocal Cords**:
- Vocal cords are located in the larynx, which is responsible for sound production.
- **Match**: (H) Vocal cords → (v) Larynx

### Final Matches:
- A → iii
- B → iv
- C → vii
- D → vi
- E → vii
- F → ii
- G → i
- H → v

### Summary of Matches:
- A (Trachea) → iii (Cartilaginous rings)
- B (Respiratory centre) → iv (Medulla oblongata)
- C (Yeast) → vii (Ethanol)
- D (Insects) → vi (Tracheal respiration)
- E (Fish) → vii (Branchial respiration)
- F (Biologically useful energy) → ii (ATP)
- G (100 mm Hg) → i (PO2 in alveolar air)
- H (Vocal cords) → v (Larynx)
