Why is a binary search the most effective way tosearch a sorted dataset?(A) The item searched for bubbles to thebeginning of the dataset after one pass.(B) It uses machine learning with each pass ofthe data to learn where the data is locatedin the file.(C) It eliminates half the dataset with eachiteration of the search.(D) It merges sections of data to only have tosearch one section with each iteration.
