The element M in the complex ion MF6^3- has a coordination number of six. Since B has only s- and p-orbitals and no d – orbitals, therefore, at the maximum it can show a coordination number of 4. Thus, B cannot form complex of the type MF6^3-, i.e., option (a) is correct.

Explanation:
When a central atom forms a complex, it can coordinate with multiple ligands to form a coordination compound. The highest coordination number that a central atom can exhibit depends on the availability of vacant orbitals in the central atom.
In the case of MF3-6, the central atom is M and it is coordinated with six F ligands. The elements B, Al, Ga, and In belong to the same group (group 13) of the periodic table and have three valence electrons. These elements can form compounds with a maximum coordination number of 6 because they have vacant d orbitals that can accommodate the additional ligands.
However, Boron (B) does not have any vacant d orbitals and can form compounds with a maximum coordination number of 4. Therefore, it is not likely to act as a central atom in MF3-6.
In summary, the availability of vacant d orbitals in the central atom determines the highest coordination number it can exhibit, and Boron does not have any vacant d orbitals, making it unlikely to act as a central atom in MF3-6.

Introduction:
The coordination number of a central atom in a compound is the number of atoms, ions or molecules bonded to the central atom. The highest coordination number depends on the availability of vacant orbitals in the central atom.
Option Analysis:
a) B: Boron can exhibit a coordination number of up to 6 due to its empty 2p orbitals. Therefore, it is likely to act as a central atom in MF3-6.
b) Al: Aluminum can exhibit a coordination number of up to 6 due to its empty 3p orbitals. Therefore, it is likely to act as a central atom in MF3-6.
c) Ga: Gallium can exhibit a coordination number of up to 6 due to its empty 4p orbitals. Therefore, it is likely to act as a central atom in MF3-6.
d) In: Indium can exhibit a coordination number of up to 6 due to its empty 5p orbitals. Therefore, it is likely to act as a central atom in MF3-6.
Conclusion:
All of the given elements are likely to act as a central atom in MF3-6 as they all have empty orbitals. Therefore, the answer is none of the above.
