Answer Details

The given sentence is in the past tense, and it's a conditional sentence. The blank space in the sentence requires a phrase that indicates the unreal condition that would have resulted in a different outcome. Out of the given options, the phrase that best completes the sentence is "would you." The complete sentence becomes "You wouldn't have come if you had known, would you?" The phrase "would you" is used to form a tag question at the end of a sentence, which seeks confirmation or agreement from the listener. In this case, the speaker is asking for confirmation that the person wouldn't have come if they had known something. Therefore, the correct answer is option A, "would you."
