Options

A. i- c , ii - d , iii - a , iv - b
B. i-d , ii - a , iii - b , iv - c
C. i - b , ii - c , iii - d , iv - a
D. i - d , ii - b , iii - a , iv - c

Answer

To solve the question of matching organisms with their appropriate reproductive structures, we will analyze each organism and identify the correct reproductive structure associated with it.

### Step-by-Step Solution:

1. **Identify the Reproductive Structure for Algae:**
- Algae reproduce asexually through structures known as **zoospores**.
- **Match:** Algae → Zoospore (Option D).

2. **Identify the Reproductive Structure for Penicillium:**
- Penicillium is a type of fungus that reproduces asexually via structures called **conidia**.
- **Match:** Penicillium → Conidia (Option B).

3. **Identify the Reproductive Structure for Sponge:**
- Sponges belong to the phylum Porifera and reproduce asexually through structures known as **gemmules**.
- **Match:** Sponge → Gemmule (Option A).

4. **Identify the Reproductive Structure for Hydra:**
- Hydra reproduces asexually through a process called **budding**, where a new individual develops from a bud on the parent organism.
- **Match:** Hydra → Buds (Option C).

### Summary of Matches:
- Algae → Zoospore (D)
- Penicillium → Conidia (B)
- Sponge → Gemmule (A)
- Hydra → Buds (C)

### Final Matching:
- i. Algae → d. Zoospore
- ii. Penicillium → b. Conidia
- iii. Sponge → a. Gemmule
- iv. Hydra → c. Buds

### Conclusion:
The correct matches are:
- Algae (i) with Zoospore (d)
- Penicillium (ii) with Conidia (b)
- Sponge (iii) with Gemmule (a)
- Hydra (iv) with Buds (c)

Thus, the correct answer is option 4: D, B, A, C.
