Explanation:
the pheny acetate, is an ester in an aromatic ring. We have the bencene and in one of the carbon, it's the acetate ion.
Now, the acetate has two oxygens with at least one pair of electrons that are available to do resonance in all the structure of the aromatic ring, because the aromatic ring has double bonds all over the ring, and can have resonance with the electrons of the oxygens.
This resonance structure can be in all the ring, or just in some positions of the ring. In this case the ortho position, which is the carbon 2. So we only can have two or three resonance structure. See the picture below for resonance.
