**Why the Correct Answer is Right**
The correct answer is related to the primary cause of pseudomembranous colitis, which is the overgrowth of **Clostridioides difficile** following the use of broad-spectrum antibiotics. These antibiotics disrupt the balance of the gut microbiota, leading to an overgrowth of **C. difficile**, which produces **toxins** that cause the condition.
**Why Each Wrong Option is Incorrect**

**Option C:** Incorrect because, although it might be related to gastrointestinal issues, it is not the primary association with pseudomembranous colitis.
**Option D:** Incorrect as it is not directly related to the condition in question.
**Clinical Pearl / High-Yield Fact**
