Hope this helps

Opened

Explanation:

File is defined as object that holds information, commands ,data etc and allotted with specific name known as file name.A file needs to be opened for performing functions like reading, writing changing elements, saving any changes made  or closing etc.Other options are incorrect because buffer is used for holding information before using it for short period of time. Closing action can be performed only after opening a file. Initialization is defining any value that is required in program.Thus , the correct option is opened.
