**Core Concept**
Nasal angiofibroma is a rare, benign vascular tumor that primarily affects adolescent males. It is characterized by its rapid growth and potential for significant morbidity due to its location in the nasal cavity and surrounding structures.

**Why the Correct Answer is Right**
Nasal angiofibroma typically presents in the second decade of life, with the majority of cases occurring between 10 and 20 years of age. This age range is thought to be related to the hormonal influence of androgens, which may promote the growth of the tumor. The tumor's rapid growth and high vascularity can lead to significant bleeding and nasal obstruction, necessitating prompt surgical intervention.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because nasal angiofibroma is not typically seen in young children, as its growth is influenced by androgens.
**Option B:** This option is incorrect because while nasal angiofibroma can occur in adults, it is much less common in this age group than in adolescents.
**Option C:** This option is incorrect because nasal angiofibroma is not typically seen in older adults, as its growth is influenced by androgens, which are more prevalent in younger males.

**Clinical Pearl / High-Yield Fact**
Nasal angiofibroma is often referred to as the "most common benign tumor in adolescent males" due to its high prevalence in this age group. Its rapid growth and potential for significant morbidity make prompt recognition and treatment essential.

**Correct Answer:** C. 10-20 years of age.
