**Core Concept**
Follicular cysts of the ovary are a type of ovarian cyst that forms when a follicle in the ovary fails to rupture and release an egg during ovulation. They are a common type of ovarian cyst and are influenced by hormonal changes, particularly the gonadotropins follicle-stimulating hormone (FSH) and luteinizing hormone (LH).

**Why the Correct Answer is Right**
Option C states that follicular cysts are independent of gonadotropins for growth. This is incorrect because follicular cysts are actually dependent on gonadotropins, particularly FSH, for their growth and maintenance. FSH stimulates the growth of follicles in the ovary, and an increase in FSH levels can lead to the formation of follicular cysts. In contrast, corpus luteum cysts are more likely to be independent of gonadotropins for growth.

**Why Each Wrong Option is Incorrect**
**Option A:** Functional cysts of the ovary are indeed a type of follicular cyst, so this option is incorrect because it is a true statement about follicular cysts.
**Option B:** Follicular cysts are indeed most common in young, menstruating women, as they are often related to normal ovulatory cycles. This option is incorrect because it is a true statement, but the question asks for an exception.
**Option D:** Women with cystic fibrosis may have an increased propensity to develop ovarian cysts, including follicular cysts, due to the underlying hormonal and metabolic changes associated with the condition.

**Clinical Pearl / High-Yield Fact**
A key clinical point to remember is that follicular cysts are often asymptomatic and may resolve spontaneously, but they can also cause symptoms such as pelvic pain and abdominal bloating. If a large follicular cyst is present, it may require surgical intervention to prevent complications.
