Ctenophores are

Options

A. Hermaphrodite
B. Diocious
C. Heterocious
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Ctenophores**: Ctenophores, also known as comb jellies, are a group of marine invertebrates belonging to the phylum Ctenophora. They are characterized by their gelatinous bodies and distinctive comb-like cilia that they use for locomotion.

2. **Reproductive Characteristics**: The question asks about the reproductive nature of ctenophores. We need to analyze the options provided:
- **Hermaphrodite**: This term refers to organisms that possess both male and female reproductive organs. Ctenophores are known to be hermaphroditic, meaning they have both reproductive systems in the same individual.
- **Diaceous**: This term refers to organisms that are unisexual, meaning they have either male or female reproductive systems, but not both. Ctenophores do not fall into this category.
- **Heteroaceous**: This term is typically used in the context of parasites that require two different hosts to complete their life cycle. This is not applicable to ctenophores.
- **All of these**: This option suggests that ctenophores could be hermaphrodite, diaceous, and heteroaceous at the same time, which is incorrect.

3. **Conclusion**: Since ctenophores are hermaphroditic, the correct answer to the question "Ctenophores are?" is option 1: Hermaphrodite.

**Final Answer**: Ctenophores are hermaphrodite (Option 1).
