Here are the essential concepts you must grasp in order to answer the question correctly.
Oxidation State
The oxidation state, or oxidation number, is a measure of the degree of oxidation of an atom in a chemical compound. It is an indicator of the number of electrons that an atom has gained, lost, or shared when forming a compound. Determining the oxidation state involves assigning electrons based on electronegativity and known oxidation states of other atoms in the molecule.

Palladium Chemistry
Palladium is a transition metal known for its ability to form complexes and participate in catalytic cycles. In organic chemistry, palladium often exists in oxidation states of 0, +2, and occasionally +4. Understanding palladium's common oxidation states and its coordination environment is crucial for determining its oxidation state in compounds.

Acetate Ligand
Acetate (AcO) is a common ligand in coordination chemistry, derived from acetic acid. It typically carries a -1 charge, which influences the oxidation state of the metal it coordinates with. In complexes, acetate can act as a bridging ligand, affecting the electron count and oxidation state of the central metal atom, such as palladium in this case.
