Which command saves data to a file?

• A. Writefile command
• B. Save data to file
• C. Write data
• D. Openfile command

Answer: (A)

Saving data to storage happens through a write operation aimed directly at the file. The Writefile command does exactly that: it performs the action of writing the data into a file so it becomes part of the file on disk. The other options aren’t actual write-to-file commands: one is just a description (“Save data to file”), another is ambiguous about where the writing goes (“Write data”), and opening a file doesn’t save anything by itself—it just prepares the file for subsequent reading or writing. In typical file I/O, you open the file, write data, and then close it; the Writefile command is the one that carries out the step of saving the data into the file.
