From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences.
You had better ...it otherwise you will have yourself to blame

Answer Details

The best option to complete this sentence is "do." The phrase "you had better" is used to give advice or warn someone about something that may happen if they do not act. In this sentence, the speaker is telling the listener that they should take a certain action to avoid negative consequences. The phrase "otherwise you will have yourself to blame" indicates that if the listener does not take this action, they will be responsible for any negative consequences that occur. The verb that follows "had better" should be in the base form, which is "do." The other options do not fit the sentence structure or convey the correct meaning. "To be doing" implies that the action is already in progress, which does not make sense in this context. "To do" is grammatically correct, but it is not as strong as "do" in conveying the urgency of the situation. "Done" is in the past tense and does not fit the sentence's conditional structure.
