Which of the following molecules has a linear shape according to VSEPR theory?

Which of the following conclusions is best supported by the evidence that in molecules exhibiting resonance, such as the carbonate ion (CO3²⁻), the observed bond lengths are intermediate between those of typical single and double bonds?

In diatomic molecules, an increased bond order typically indicates a stronger, shorter bond. Empirically, for many carbon–carbon bonds, the single bond energy is approximately 350 kJ/mol and the double bond energy is near 610 kJ/mol. Based on this information, approximately how many times stronger is a double bond compared to a single bond?
