**Core Concept**
Peritrichous flagellae refer to the arrangement of flagella around the entire surface of a bacterial cell. This type of flagellar arrangement is characteristic of certain gram-negative bacteria. The presence and arrangement of flagella are important for bacterial identification and motility.

**Why the Correct Answer is Right**
The correct answer is related to the type of bacteria that exhibits peritrichous flagellae. In bacteria, flagella are crucial for motility, and their arrangement can vary. Peritrichous flagellae are typically found in bacteria that require rapid and versatile movement, such as *Escherichia coli* and other enteric bacteria.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe the type of bacteria with peritrichous flagellae.
**Option B:** Similarly, this option is incorrect as it does not correspond with the bacterial type known for peritrichous flagellation.
**Option C:** This option is also incorrect as it represents a different characteristic or type of bacteria.

**Clinical Pearl / High-Yield Fact**
Peritrichous flagellae are a key feature of certain pathogenic bacteria, aiding in their identification and understanding of their pathogenicity. Recognizing the type of flagellar arrangement can be crucial in clinical microbiology for diagnosing infections.

**Correct Answer:** D. Escherichia coli
