**Core Concept**
The question is testing the student's knowledge of the premalignant potential of different types of polyps found in the gastrointestinal tract. **Hyperplastic polyps** and **inflammatory polyps** are generally considered to be non-neoplastic and non-premalignant, whereas **adenomatous polyps** and **serrated polyps** have the potential to progress to colorectal cancer.

**Why the Correct Answer is Right**
Hyperplastic polyps are characterized by an increase in the number of cells in the epithelial lining of the colon, but this is not associated with an increased risk of cancer. They are usually small, solitary, and found in the distal colon and rectum. In contrast, adenomatous polyps are composed of glandular tissue and have the potential to progress to colorectal cancer if left untreated.

**Why Each Wrong Option is Incorrect**
**Option A:** Adenomatous polyps are premalignant because they have the potential to progress to colorectal cancer.
**Option B:** Serrated polyps, including sessile serrated adenomas and traditional serrated adenomas, are also premalignant because they can progress to colorectal cancer.
**Option C:** Villous adenomas are a type of adenomatous polyp that has a high risk of developing into colorectal cancer.

**Clinical Pearl / High-Yield Fact**
It's essential to differentiate between premalignant and non-premalignant polyps to determine the appropriate management strategy. Polyps with a high risk of progression to cancer, such as adenomatous polyps, require removal and histopathological examination.

**Correct Answer: A. Hyperplastic polyps.**
