Which command is appropriate?

Hint 1: Focus on the requirement

Identify what must change and what must remain unchanged. Then choose the command whose scope matches that requirement.

Hint 2: Check each command's role

Separate commands that display information, change state, remove data, or affect a child process.

journalctl -p err: Correct. -p err selects err and all more severe priorities.
journalctl -u err: Incorrect. -u would interpret err as a unit name.
journalctl -b err: Incorrect. -b is a boot filter.
journalctl -t err: Incorrect. -t filters an identifier.
