A prefix is a word particle (an affix, in particular) that is added before the stem of a word such that, by its addition, the meaning of the word changes.
One such prefix is “mis”, which carries the sense of “wrong” or “bad”. In this way, adding the prefix “mis” to “interpret”, that is to say, “misinterpret”, the word comes to mean “to interpret wrongly”.
I would say that the fourth answer choice, "to interpret wrong," would be the best choice because the prefix mis- means wrongly. (For example, misinform means to give the wrong information to someone.)
