Answer

To solve the question "Deuterostomate and enterocoelomate invertebrate is," we will follow these steps:

### Step 1: Understand the Terms

- **Enterocoelomate**: This refers to organisms that have a true body cavity (coelom) that is formed by the out-pocketing of the embryonic gut.

### Step 2: Identify Examples
- **Examples of Deuterostomes**: Echinoderms (like starfish) and Chordates (like vertebrates).
- **Examples of Enterocoelomates**: Echinoderms and Chordates are also enterocoelomates.

### Step 3: Analyze the Options
- The question provides options, which include:
1. Pila (Mollusca)
2. Ascaris (Aschelminthes)
3. Aphrodite (Annelida)
4. Asterias (Echinodermata)

### Step 4: Determine the Correct Answer
- Among the options, **Asterias** (which belongs to Echinodermata) is both a deuterostome and an enterocoelomate.
- Therefore, the correct answer is **Asterias**.

### Final Answer
The deuterostomate and enterocoelomate invertebrate is **Asterias**.
