In order to display all currently mounted filesystems, which of the following commands could be used? (Choose TWO correct answers.)

/proc/self/mounts is a kernel-maintained virtual file reflecting the active mount namespace of the calling process, listing every mounted filesystem with its device, path, type, and options in real time.

`free` reports system memory and swap usage and has no output related to mounted filesystems.

Running `mount` with no arguments reads and prints /proc/self/mounts (or /proc/mounts), producing a human-readable list of all currently active mount points.

`lsmounts` is not a standard Linux command and is not present in mainstream distributions.

/proc/filesystems lists filesystem types the running kernel supports or has loaded as modules, not the filesystems that are currently mounted.
