See explanation.
Step-by-step explanation:
Hello,
In this case, since both carbon and oxygen need to complete the octet, that is sharing eight electrons in total, since carbon has four valence electrons it has a double bond with one oxygen so it also allows the first oxygen to attain the octet; moreover, for the other oxygen, there also a double bond in order to complete the octet for carbon and for the second oxygen as shown on the attached picture.
Best regards.
