Answer

To solve the matching question regarding Taenia, we need to understand the functions of different structures associated with it. Here’s a step-by-step breakdown of the matching process:

### Step-by-Step Solution:

1. **Identify Mahle's Glands**:
- Mahle's glands, also known as shell glands, are responsible for lubricating the uterine passage.
- **Match**: Mahle's glands (a) → Lubricate passage of capsules into uterus (iii).

2. **Identify Vitelline Glands**:
- Vitelline glands are located in the female genital tract and are involved in the formation of the egg membrane and capsule formation around the zygote.
- **Match**: Vitelline glands (b) → Capsule formation around zygote (v).

3. **Identify Mesenchymal Cells**:
- Mesenchymal cells are involved in the formation of the tegument, which is a thick protective covering in flatworms.
- **Match**: Mesenchymal cells (c) → Tegument formation (i).

4. **Identify Flame Cells**:
- Flame cells are specialized cells that play a role in osmoregulation and excretion in flatworms.
- **Match**: Flame cells (d) → Osmoregulation and excretion (ii).

### Final Matching:
- (a) Mahle's glands → (iii) Lubricate passage of capsules into uterus
- (b) Vitelline glands → (v) Capsule formation around zygote
- (c) Mesenchymal cells → (i) Tegument formation
- (d) Flame cells → (ii) Osmoregulation and excretion

### Summary of Matches:
- A → iii
- B → v
- C → i
- D → ii
