Final answer:

The correct formula for Manganese (III) Fluoride is MnF₃, as it reflects the +3 oxidation state of manganese bonding with three -1 charge fluoride ions.

Step-by-step explanation:

The correct formula for the compound Manganese (III) Fluoride is MnF₃. This is because manganese in its +3 oxidation state (as indicated by the (III) in the name) will combine with fluoride ions which have a -1 charge. Each manganese ion can bond with three fluoride ions to balance the +3 charge of manganese with the total -3 charge from the three fluoride ions.

Therefore, the correct answer is:
c. MnF₃

Also, to address a related concept, the coordination number of the Mn³+ ion (which indicates the number of ions of opposite charge that surround the manganese ion in a crystal lattice) would depend on the specific structure of the manganese compound.
