Answer:
The correct answer is letter "C": Search Box.
Step-by-step explanation:
The "Search Box" is a tool that allows looking for different types of files stored in the hard drive. For this matter, it is necessary to know under what name the file was saved otherwise it will be impossible to find it. Misspellings could make this task difficult but, fortunately, the tool is not case sensitive so it does not matter if the file name is in upper or lower case.
