The correct statement is:
**The bond in nitrogen gas is the most difficult to break.**
Nitrogen gas (N₂) has a strong triple bond, which results in a very high bond energy. Comparatively, iodine (I₂) has a much weaker single bond, and fluorine (F₂) also has a weaker bond than nitrogen due to its high electronegativity and the resulting repulsions between the lone pairs on the fluorine atoms. Therefore, nitrogen gas has the highest bond energy among these three gases.
