Hint: There are certain rules that govern the IUPAC naming of such complex coordination compounds. Those standard rules are to be followed accurately while naming and precisely , keeping in mind the small details .

Complete answer:
so, lets recall briefly the rules for IUPAC naming of coordination compounds:
 $ 1. $ Remember that the name of the ligand comes before the central atom.
 $ 2. $ The ligands first are written on the basis of their charge order: Neutral, negative, positive. And if the same charge ligands are present, then ligands are written in alphabetical order.
 $ 3. $ If the ligand already contains a numerical prefix , then the terms like – bis, tris, tetrakis are used before the name of that ligand.
 $ 4. $ Neutral ligands are given common names but there are few exceptions for the functional groups like $ N{H_3} $ - ammine, $ {H_2}O $ - aqua.
 $ 5. $ While writing the central atom, always remember to mention its oxidation state in parentheses.
So , using above rules, let’s write the name of our given compound:
First, we will write ligand name and then central atom:
So,the name of our ligand will be-
Tetraammineplatinium $ (IV) $ bis(oxalato) paladate $ (II) $ .
Always keep in mind the rules while naming the coordination compound.
Therefore the correct option is C.

Note:
Always keep in mind that if the complex is an anion, then the central atom always ends with the suffix – ate . like in our given coordination compound, the central atom palladium ends with –ate, i.e paladate , since it is in the anion complex. Whereas, in the cation complex, an atom is named according to its common name with some few exceptions.
