C. capsule
D. all of these

Answer

To solve the question "Fruit developed from bicarpellary syncarpous ovary having a false septum is:", we will analyze the terms and options provided.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Bicarpellary**: This means the ovary has two carpels. Each carpel is a part of the female reproductive structure of the flower.
- **Syncarpous**: This indicates that the carpels are fused together to form a single compound ovary.

2. **Identify the Characteristics of the Fruit**:
- The question specifies that the fruit develops from a bicarpellary syncarpous ovary and has a false septum. A false septum is a partition that is not a true wall but rather a structure that divides the ovary into sections.

3. **Evaluate the Options**:
- **Silica**: This is a type of fruit that develops from a bicarpellary syncarpous ovary. It typically has a false septum (known as a replum) that divides the fruit into two chambers.
- **Acne**: This is a small, one-seeded fruit that develops from a monocarpillary ovary, which does not fit the bicarpellary requirement.
- **Capsule**: This fruit can develop from a polycarpillary ovary (more than two carpels) and does not match the bicarpellary syncarpous condition.
- **All of these**: This option is incorrect since not all the options fit the description.

4. **Conclusion**:
- Based on the definitions and characteristics, the correct answer is **Silica**. This type of fruit is specifically known for developing from a bicarpellary syncarpous ovary and having a false septum.

### Final Answer:
The fruit developed from a bicarpellary syncarpous ovary having a false septum is **Silica**.
