**Core Concept**
Small bowel diverticula are outpouchings of the intestinal wall, most commonly occurring in the jejunum. They are often associated with increased intraluminal pressure, which can lead to herniation of the mucosa through a weakness in the muscularis layer.

**Why the Correct Answer is Right**
Diverticula formation is thought to result from a combination of factors, including high intraluminal pressure, decreased blood flow, and weakening of the intestinal wall. The increased pressure can cause herniation of the mucosa through the weak points, leading to the formation of diverticula. The jejunum is particularly prone to diverticula due to its relatively higher intraluminal pressure compared to the ileum.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not accurately describe the pathophysiology of small bowel diverticula.
**Option B:** This option is incorrect as it is not a recognized risk factor for small bowel diverticula.
**Option C:** This option is incorrect as it is not a characteristic feature of small bowel diverticula.

**Clinical Pearl / High-Yield Fact**
It is essential to note that small bowel diverticula can lead to complications such as diverticulitis, bleeding, and obstruction, making prompt diagnosis and management crucial.

**Correct Answer:** C.
