Answer:

The most stable possible Lewis structures are in the picture

Explanation:

In the left of the picture are three C=O bonds and two O-H bond. By formula C₄H₄O₅ there are missing two hydrogens and one carbon that most be a methylene group (CH₂). Thus, the most logical ways to bond the substructures are drawing in the picture having in mind that O-O bond are not stable.

I hope it helps!
