**Core Concept**
The SRY gene plays a crucial role in sex determination, specifically in the development of testes in the embryo. It encodes a transcription factor that binds to specific DNA sequences, initiating the testis-determining pathway. The SRY gene is a key player in the sex-determining region of the Y chromosome.

**Why the Correct Answer is Right**
The SRY gene is located on the short arm of the Y chromosome (Yp) and is essential for the initiation of testis development. In the absence of SRY, the default pathway leads to ovarian development. The SRY protein interacts with other transcription factors, including SOX9, to activate the testis-determining gene cascade. The precise location of the SRY gene on the Y chromosome is critical for its function in sex determination.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not provided.
**Option B:** Incorrect, as the SRY gene is not located on the X chromosome.
**Option C:** Incorrect, as the SRY gene is not located on the autosomes (non-sex chromosomes).

**Clinical Pearl / High-Yield Fact**
It's essential to remember that mutations in the SRY gene can lead to sex reversal, a condition where an individual with a Y chromosome develops ovaries instead of testes. This highlights the critical role of the SRY gene in sex determination and the importance of precise genetic control during embryonic development.

**Correct Answer:** C. The SRY gene is located on the Y chromosome.
