**Core Concept**
Rhinosporidiosis is a chronic, granulomatous infection caused by Rhinosporidium seeberi, a fungus-like organism that primarily affects the mucous membranes of the nose, eyes, and urogenital tract. The infection is characterized by the formation of polyps and the presence of characteristic sporangia.

**Why the Correct Answer is Right**
Rhinosporidiosis is known for its distinctive features, including the formation of polyps, the presence of sporangia, and a tendency to recur after treatment. The infection typically presents with localized swelling, bleeding, and discharge. The sporangia of Rhinosporidium seeberi contain numerous sporozoites, which are responsible for the spread of the infection.

**Why Each Wrong Option is Incorrect**
**Option A:** Formation of polyps is a characteristic feature of rhinosporidiosis.
**Option B:** Presence of sporangia is a hallmark of the disease.
**Option C:** Tendency to recur after treatment is a notable aspect of rhinosporidiosis.

**Clinical Pearl / High-Yield Fact**
Rhinosporidiosis is often mistaken for other conditions such as rhinoscleroma, sarcoidosis, or tuberculosis, due to its similar presentation. However, the presence of sporangia and the characteristic polypoid lesions can help differentiate it from these conditions.

**Correct Answer:** D.
