Best answer
Correct choice is (a) -z

For explanation: cp command has many options available, each of which performs a unique task. (-i)  is used for interactive copying (i.e.) it warns the user before overwriting the destination file.  (-R) is used for copying the entire directory structure into another directory structure. (-u) copies only when the source file is newer than the destination file.
