Answer

To solve the matching question, we need to pair each plant hormone with its corresponding description. Let's break it down step by step:

### Step 1: Identify the Hormones and Their Functions
We have five hormones to match:
- Auxin
- Cytokinin
- Gibberellin
- Ethylene
- Abscisic Acid

### Step 2: Match Each Hormone with Its Description
1. **Auxin (a)**:
- Function: Auxin is primarily involved in **apical dominance**, which means it promotes the growth of the apical bud while inhibiting the growth of lateral buds.
- Match: **A3 (Apical dominance)**

2. **Cytokinin (b)**:
- Function: Cytokinins were discovered from **herring sperm DNA** and are known for promoting cell division and growth.
- Match: **B1 (Herring sperm DNA)**

3. **Gibberellin (c)**:
- Function: Gibberellins are known to **induce amylase synthesis**, which is important for seed germination and growth.
- Match: **C5 (Induces amylase synthesis)**

4. **Ethylene (d)**:
- Function: Ethylene is associated with **epinasty**, which is the downward bending of plant parts.
- Match: **D4 (Epinasty)**

5. **Abscisic Acid (e)**:
- Function: Abscisic acid acts as an **inhibitor of growth**, suppressing growth and maintaining dormancy in plants.
- Match: **E2 (Inhibitor of growth)**

### Step 3: Compile the Final Matches
Now that we have matched each hormone with its description, we can summarize the combinations:
- A (Auxin) → 3 (Apical dominance)
- B (Cytokinin) → 1 (Herring sperm DNA)
- C (Gibberellin) → 5 (Induces amylase synthesis)
- D (Ethylene) → 4 (Epinasty)
- E (Abscisic acid) → 2 (Inhibitor of growth)

### Final Answer
The correct combination is:
- A3, B1, C5, D4, E2
