**Question:**

Which structure likely represents a GPCR?

**Options:**

- Option A: A colorful helical structure with a twisting pattern.
- Option B: A structure composed of yellow, parallel beta-sheets forming a barrel-like shape.
- Option C: A complex, globular structure with both helices and sheets intertwined, colored mainly in red and blue.
- Option D: A helical structure featuring several transmembrane helices, colored in a spectrum from blue to red. The helices are numbered, likely indicating segments.

**Answer Choices:**

- ○ C
- ○ D
- ○ A
- ○ B

**Explanation:**

GPCRs, or G-protein-coupled receptors, typically have a characteristic structure of seven transmembrane helices. Option D, which shows this distinct pattern, is most consistent with the structure of a GPCR.
