C. e-I, c-ii, b-iii, d-iv, b-v
D. All of the above

Answer

To solve the matching question, we need to identify the correct reproductive classification for each organism listed in Column I and match it with the appropriate term in Column II. Here’s a step-by-step breakdown:

### Step 1: Understand the Terms in Column II
1. **Monoecious**: Organisms that have both male and female reproductive organs in the same individual.
2. **Dioecious**: Organisms that have male and female reproductive organs on different individuals.
3. **Hermaphrodite**: Similar to monoecious; organisms that possess both male and female reproductive organs in the same individual.
4. **Unisexual**: Organisms that are either male or female, but not both.
5. **Bisexual**: Organisms that have both male and female reproductive organs in the same individual (synonymous with hermaphrodite).

### Step 2: Analyze Each Organism in Column I
1. **Sponge**: Sponges are known to be hermaphroditic, meaning they have both male and female reproductive organs. Thus, it can be classified as **Monoecious (a)**.
2. **Leech**: Leeches are also hermaphroditic, possessing both male and female reproductive organs. Therefore, they are classified as **Monoecious (a)** or **Bisexual (e)**.
3. **Cockroach**: Cockroaches are dioecious, meaning they have distinct male and female individuals. Thus, they are classified as **Dioecious (b)**.
4. **Frog**: Frogs are also dioecious, with separate male and female individuals. Hence, they are classified as **Dioecious (b)**.
5. **Date Palm**: Date palms are dioecious, with male and female flowers on separate plants. Therefore, they are classified as **Dioecious (b)**.

### Step 3: Match the Organisms with the Correct Terms
- **Sponge**: Monoecious (a)
- **Leech**: Monoecious (a) or Bisexual (e)
- **Cockroach**: Dioecious (b)
- **Frog**: Dioecious (b)
- **Date Palm**: Dioecious (b)

### Step 4: Present the Final Matches
Based on the analysis:
- (i) Sponge - (a) Monoecious
- (ii) Leech - (a) Monoecious or (e) Bisexual
- (iii) Cockroach - (b) Dioecious
- (iv) Frog - (b) Dioecious
- (v) Date Palm - (b) Dioecious

### Final Answer
The correct combinations are:
- (i) Sponge - (a)
- (ii) Leech - (a) or (e)
- (iii) Cockroach - (b)
- (iv) Frog - (b)
- (v) Date Palm - (b)
