File path

Explanation:

Literally, file path implies the location of a particular file

This in other words means that: the location of a file is defined or specified by its path.

Take for instance a text file named abc located at the desktop could have its file location to be C:\Users\HP\Desktop\abc.txt

Other options such as file type means the type of the file which could be a text file, an image, etc. and file extension is a suffix that indicates the file type (e.g. jpg, txt, png, etc).

So, from the list of given options; file path answers the question.
