Steghide can be used to extract hidden data from a file when the correct passphrase is known. 'steghide extract -sf picture.jpg' command is used for extraction, where '-sf' flag specifies the steganography file to extract data from. Without the correct passphrase, extraction will not be possible. The other options are incorrect because -ef is for embedding files, -xf specifies extraction, but without a file it makes no sense in this context, and simply running 'steghide' without any flags or options will just display the usage information, not perform any meaningful operation.
