**Core Concept**
The genital ridge is a critical structure in the development of the reproductive system. It arises from the intermediate mesoderm, a layer of cells that gives rise to various organs, including those of the urinary and reproductive systems.

**Why the Correct Answer is Right**
The genital ridge develops from the intermediate mesoderm, specifically from the nephrogenic cord, a precursor to the kidneys and the genital system. This process occurs during embryonic development, around 4-6 weeks of gestation. The genital ridge eventually differentiates into the gonads, which can develop into either ovaries or testes, depending on the presence of sex-determining region Y (SRY) protein.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not specified, so we cannot evaluate its correctness.
**Option B:** This option is also not specified, so we cannot evaluate its correctness.
**Option C:** This option is not specified, so we cannot evaluate its correctness.
**Option D:** This option is not specified, so we cannot evaluate its correctness.

**Clinical Pearl / High-Yield Fact**
The development of the genital ridge from the intermediate mesoderm is a critical step in the formation of the reproductive system. Understanding this process is essential for diagnosing and managing disorders related to reproductive development.

**Correct Answer: C. Genital ridge develops from the intermediate mesoderm.**
