Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the infection known as a "sty." We need to identify what part of the eye is affected by this infection.

2. **Identifying the Affected Area**: A sty is specifically an infection that occurs in the eye. It is important to note that it is related to a specific type of gland.

3. **Recognizing the Gland**: The gland involved in a sty is known as the gland of Zeis. This gland is a modified sebaceous gland that is associated with the hair follicles of the eyelashes.

4. **Mechanism of Infection**: When the gland of Zeis becomes infected, it can lead to an increased secretion of sebum. This can result in the accumulation of a white material around the edge of the eyelid, which is characteristic of a sty.

5. **Eliminating Incorrect Options**: The question may provide other options such as "sclerotic," "choroid," and "retina." These terms refer to other parts of the eye but are not related to the infection of a sty. Therefore, they can be ruled out as incorrect answers.

6. **Conclusion**: The correct answer to the question is that a sty is an infection of the gland of Zeis.

**Final Answer**: Sty is an infection of the gland of Zeis.
