# The species \(\text{CO}\), \(\text{CO}_2\), and \(\text{CO}_3^{2-}\) all contain carbon-to-oxygen bonds. Which of the following correctly ranks these species in order of decreasing \(\text{C}-\text{O}\) bond length (from longest to shortest)?

The species \(\text{CO}\), \(\text{CO}_2\), and \(\text{CO}_3^{2-}\) all contain carbon-to-oxygen bonds. Which of the following correctly ranks these species in order of decreasing \(\text{C}-\text{O}\) bond length (from longest to shortest)?

- **A.** \(\text{CO}_3^{2-} > \text{CO}_2 > \text{CO}\)
- **B.** \(\text{CO}_3^{2-} > \text{CO} > \text{CO}_2\)
- **C.** \(\text{CO} > \text{CO}_2 > \text{CO}_3^{2-}\)
- **D.** \(\text{CO} > \text{CO}_3^{2-} > \text{CO}_2\)
