Adult annelids have symmetry similar to that of

Options

A. Adult coelenterate
B. Most of sponges
C. Adult echinodermates
D. Chordates

Answer

To solve the question regarding the symmetry of adult annelids, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Annelids**:
- Annelids are a group of segmented worms, which include earthworms and leeches.
- They exhibit a specific type of body symmetry.

2. **Identifying the Symmetry of Annelids**:
- Adult annelids possess **bilateral symmetry**. This means that their body can be divided into two equal halves along a single plane, typically down the middle.

3. **Analyzing the Options**:
- **Option 1: Adult Cnidarians**: Cnidarians, such as jellyfish and corals, exhibit **radial symmetry**, which is different from bilateral symmetry.
- **Option 2: Most Sponges**: Sponges are known for being **asymmetrical**, meaning they lack any definite symmetry.
- **Option 3: Adult Echinoderms**: Echinoderms, like starfish, have **pentaradial symmetry** as adults, which is also not bilateral.
- **Option 4: Chordates**: Chordates, which include vertebrates like mammals, birds, and fish, also exhibit **bilateral symmetry**.

4. **Conclusion**:
- Since adult annelids have bilateral symmetry, the correct answer is **Option 4: Chordates**, as they share the same type of symmetry.

### Final Answer:
The symmetry of adult annelids is similar to that of **Chordates**.
