Answer:

B.

Explanation:

Carbon = 4

Oxygen = 6x 2

Total e- = 16 - 4 ( the number of initial single bonds)

Final number of available e- = 12

The total number of available electrons is 12 and is distributed to oxygen atoms having 6 e- each. To make C octet each oxygen atoms donates its pair of electrons to form another bond. So we have a double bond on each side making C octet and two O atoms.
