Long and non motile cilia like process, in epidydimis and internal ear are  

Options

A. Cilia
B. Stereocilia
C. flagella
D. microvilli

Answer

To solve the question regarding the long and non-motile cilia-like processes found in the epididymis and internal ear, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a specific type of structure that is long, non-motile, and resembles cilia, located in the epididymis and internal ear.

2. **Analyze the Options**:
- **Cilia**: These are typically motile structures that help in movement and are not the correct answer since the question specifies non-motile.
- **Flagella**: These are also motile structures primarily involved in locomotion. Therefore, this option can be eliminated as well.
- **Microvilli**: These are small, finger-like projections found mainly in the small intestine and are involved in absorption. They are not the correct answer since they do not fit the description provided in the question.
- **Stereocilia**: These are long, non-motile projections that resemble cilia and are found in the epididymis and the internal ear. This option fits the description perfectly.

3. **Select the Correct Answer**: Based on the analysis, the correct answer is **stereocilia**.

### Final Answer:
The long and non-motile cilia-like process in the epididymis and internal ear are **stereocilia**.
