The compound that has resonance structures is D. Na2CO3.

Here's why:

Resonance structures occur when there are multiple valid ways for electrons to be arranged in a molecule. This is often seen in molecules with double bonds.

A. C6H12 - This is cyclohexane, a simple ring structure with no double bonds, so it does not have resonance structures.

B. CH3CHO - This is acetaldehyde, which also does not have any double bonds outside of the carbonyl group, and thus does not have resonance structures.

C. NaBr - This is sodium bromide, an ionic compound, which does not have resonance structures.

D. Na2CO3 - This is sodium carbonate, which has a carbonate ion (CO3^2-). The carbonate ion has resonance structures because the double bond in the ion can be located in multiple places around the carbon atom.
