**Core Concept**
Neisseria gonorrhoeae is a gram-negative diplococcus bacterium that causes the sexually transmitted infection gonorrhea. It primarily infects the mucous membranes of the urogenital tract and is known for its ability to evade the host's immune system.

**Why the Correct Answer is Right**
Neisseria gonorrhoeae possesses several virulence factors, including pili, which are essential for bacterial attachment to and invasion of host cells. The bacteria also express IgA protease, which helps to degrade antibodies and evade the host's immune response. Additionally, N. gonorrhoeae has developed resistance to multiple antibiotics, making treatment challenging.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe a characteristic of Neisseria gonorrhoeae.

**Option B:** This option is incorrect because it is not a true statement about N. gonorrhoeae.

**Option C:** This option is incorrect because it does not accurately describe the primary mode of transmission of N. gonorrhoeae.

**Option D:** This option is incorrect because it is not a recognized virulence factor of N. gonorrhoeae.

**Clinical Pearl / High-Yield Fact**
Neisseria gonorrhoeae is a classic example of an opportunistic pathogen that takes advantage of the host's compromised immune system. It is essential to consider the possibility of gonorrhea in patients with symptoms of urethritis or cervicitis, especially in those with a history of multiple sexual partners.

**Correct Answer:** C.
