**Core Concept**
The question tests the understanding of post-surgical complications, specifically the causes of intestinal obstruction. Intestinal obstruction can occur due to various reasons, including mechanical and non-mechanical factors.

**Why the Correct Answer is Right**
The likely cause of intestinal obstruction in this scenario is adhesions, which are bands of fibrous tissue that can form between organs or between an organ and the abdominal wall following surgery. These adhesions can cause bowel loops to become trapped, leading to obstruction.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option provided, it's challenging to address each incorrect choice directly. However, common incorrect options might include conditions like hernias, tumors, or volvulus, which, while possible causes of intestinal obstruction, are less directly related to a history of abdominal surgery than adhesions.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that adhesions are the most common cause of small bowel obstruction, especially in patients with a history of abdominal surgery.

**Correct Answer:** D. Adhesions
