Topic: Group verb,

Best Answer Explained in Below-:

In the sentence "The thief broken ______ the house," the appropriate option to complete the phrase is "into," making the correct sentence, "The thief broken into the house." The word "into" is used to indicate movement from outside to a point inside a specified space, which is precisely the scenario described: the thief is entering the house without permission, which implies a movement across the threshold from outside to inside.

Option A, "in," does not convey the action of entering; it simply indicates being present within a space. Option C, "at," also fails to demonstrate the action of entering; it refers more to a point of location rather than a movement. Lastly, option D, "among," suggests being included in a group but does not relate to entering a space. Thus, the choice of "into" is not only grammatically correct but also effectively communicates the intended action of the thief breaking in and entering the house unlawfully.
