The correct option is B Potassium pentachloro(phenyl) antimonate(V)
IUPAC naming of coordination compound:
The names of coordination compounds are derived by the following principles of nomenclature,
1. The cation is named first in both positively and negatively charged coordination entities.
2. The ligands are named in an alphabetical order before the name of the central atom/ion.
3. When coordination entity is anionic, the name of central metal atom end with 'ate' followed by its oxidation number in roman numericals.
In given compound, the charge on coordination entity is -1.
Cl− and phenyl are monodentate anionic ligand.
Thus, the oxidation state of Sb is +5.
Hence, the IUPAC name of the compound K[SbCl5Ph] is Potassium pentachloro(phenyl)antimonate(V)

IUPAC Name of Compound K[SbCl5Ph]
Explanation:
The given compound has the formula K[SbCl5Ph]. To name this compound, we need to follow the IUPAC rules for naming coordination compounds.
Step 1: Identify the cation and anion
The cation in the given compound is potassium (K+), and the anion is a complex ion [SbCl5Ph]−.
Step 2: Name the cation
The cation K+ is named as potassium.
Step 3: Name the anion
The anion [SbCl5Ph]− is a complex ion, where Sb is the central metal atom and Ph is the ligand. The ligand Ph is named as phenyl. The anion can be named using the following steps:
1. The ligands are named in alphabetical order, ignoring any prefixes like di, tri, tetra, etc. In this case, we have only one type of ligand, which is phenyl.
2. The central metal atom is named, followed by the oxidation state of the metal in parentheses. In this case, the central metal atom is antimony (Sb) with an oxidation state of +5.
3. The ligands are named using their Greek prefixes to indicate the number of each type of ligand. In this case, we have only one type of ligand, so we do not need to use any Greek prefixes.
4. The ligands are named using their full names, with the ligand name followed by the oxidation state of the ligand in parentheses. In this case, the ligand is phenyl with an oxidation state of 0.
Therefore, the anion [SbCl5Ph]− is named as pentachloro(phenyl)antimonate(V).
Step 4: Write the name of the compound
The name of the compound is obtained by combining the names of the cation and anion. Therefore, the IUPAC name of the compound K[SbCl5Ph] is potassium pentachloro(phenyl)antimonate(V).
Answer: The correct option is (B) Potassium pentachloro(phenyl) antimonate (V).

This is a salt complex (usually formed by transition elements).When we talk about the anion part, Sb has Oxidation number +5( since Phenyl group is organic and does not take part in O.N. calculation)So the name will be Potassium pentachloro(phenyl) complex of antimony, ie antimmonate
