The coccyx, commonly referred to as the tailbone, is formed by the fusion of vertebrae. Typically, there are four individual coccygeal vertebrae (Co1, Co2, Co3, Co4) that fuse together to form a single structure in adult humans.

Among the choices provided: two, four, five, and seven, the correct answer is **four**.

### Explanation
During the development and growth process in humans, these four vertebrae begin as distinct bones but gradually fuse together to create the coccyx. The coccyx serves multiple functions; it acts as an anchor for various muscles, tendons, and ligaments and helps support the pelvic organs. The coccyx's composition and structure can vary between individuals, but the typical fusion of four vertebrae is a common standard in human anatomy.

In summary, the coccyx is formed by the fusion of **four vertebrae**.
