Question sur la grammaire et la structure. Je regrette ... mon action.
Answer Details
The sentence "Je regrette ... mon action?" is a sentence in French that means "I regret ... my action?" The missing word must be an adverb that modifies the verb "regrette." The appropriate adverb to use in this context is "vivement," which means "deeply" or "strongly." Therefore, the correct option is "vivement."
