The highest stable oxidation state of Mn with F is +4, option B.

Explanation:

1. Oxidation states of Mn:
The element manganese (Mn) can exhibit various oxidation states, ranging from -3 to +7. The most common oxidation states of manganese are +2, +4, and +7.

2. Fluorine as an oxidizing agent:
Fluorine (F) is a highly electronegative element and is a powerful oxidizing agent. It readily accepts electrons to achieve a stable configuration.

3. Fluorine's electron configuration:
Fluorine has an electron configuration of 1s² 2s² 2p⁵, with 7 valence electrons. It requires one more electron to achieve a stable configuration, which is why it acts as an oxidizing agent.

4. Formation of compounds:
When manganese reacts with fluorine, it can form various compounds depending on the oxidation state of manganese. The oxidation state of manganese in a compound can be determined by assigning oxidation numbers to each element in the compound.

5. Stability of oxidation states:
The stability of different oxidation states of manganese depends on several factors such as the electronic configuration, the atomic size, and the presence of other ligands or elements.

6. Highest stable oxidation state:
In the case of manganese with fluorine, the highest stable oxidation state is +4. This is because fluorine is a highly electronegative element and can readily accept electrons to achieve a stable configuration. Manganese can donate 4 electrons to fluorine, resulting in the formation of the compound MnF₄.

7. Other oxidation states:
While higher oxidation states of manganese, such as +6 and +7, are theoretically possible, they are less stable and tend to be more reactive. These higher oxidation states are commonly observed in compounds with stronger oxidizing agents or in the presence of other ligands.

Conclusion:
In conclusion, when manganese reacts with fluorine, the highest stable oxidation state is +4. This is due to the high electronegativity of fluorine, which readily accepts electrons from manganese. Other oxidation states of manganese, such as +6 and +7, are less stable and more reactive.
