If the duct is unbranched but the secretory portion is branched, the glands are called 

Options

A. Compound branched glands
B. Simple branched glands
C. Compound glands
D. Simple glands

Answer

To answer the question, "If the duct is unbranched but the secretory portion is branched, the glands are called," we need to analyze the types of glands based on their structure.

### Step-by-Step Solution:

1. **Understand Gland Structure**: Glands can be classified based on the branching of their ducts and secretory portions. The two main components we need to focus on are the duct and the secretory portion.

2. **Identify Key Terms**:
- **Duct**: The passage through which the secretion is transported.
- **Secretory Portion**: The part of the gland that produces the secretion.

3. **Analyze the Options**:
- **Simple Glands**: These have both the duct and secretory portion unbranched. Therefore, this option is incorrect.
- **Compound Glands**: These have a branched duct system, which is the opposite of what we need. Thus, this option is also incorrect.
- **Compound Branched Glands**: These have both a branched duct and a branched secretory portion. This does not fit our requirement, so this option is incorrect as well.
- **Simple Branched Glands**: These have an unbranched duct but a branched secretory portion. This matches the description given in the question.

4. **Conclusion**: Based on the analysis, the correct answer is **Simple Branched Glands**.

### Final Answer:
The glands are called **Simple Branched Glands**.
