D. Acetabularia

Answer

To answer the question "Plant body is differentiated in hold fast, stipe and frond in," we need to identify which group of plants exhibits this type of structure.

### Step-by-Step Solution:

1. **Identify the Plant Group**: The question is asking about a plant body that has three specific structures: hold fast, stipe, and frond. These terms are commonly associated with certain types of plants.

2. **Understand the Terms**:
- **Hold Fast**: This is a structure that anchors the plant to a substrate, commonly found in algae and some non-vascular plants.
- **Stipe**: This is the stem-like structure that supports the frond; it is often seen in ferns and some algae.
- **Frond**: This refers to the leaf-like structure of ferns and some other plants.

3. **Relate to Plant Types**: The combination of hold fast, stipe, and frond is characteristic of certain algae and ferns. Specifically, it is a common feature in the structure of **Phaeophyta** (brown algae) such as kelp.

4. **Conclude the Answer**: Based on the identification of these structures, we conclude that the plant body differentiated into hold fast, stipe, and frond is found in **Phaeophyta** (brown algae).

### Final Answer:
The plant body is differentiated in hold fast, stipe, and frond in **Phaeophyta (brown algae)**.
