Compound II has the most acidic hydrogen because of the presence of two electron-withdrawing fluorine atoms, which make it more likely for the hydrogen to dissociate and release a proton. This makes the resulting ion more stable. The other compounds do not have any electron-withdrawing groups near the hydrogen atom, making them less likely to dissociate and release a proton.
