This was a cross country flight with a commercial student. After being vectored; we were cleared to land on the right parallel runway at ZZZ. Another aircraft at the airport was cleared to land on the left runway. They apparently heard the right runway as they got uncomfortably close. They corrected to the left runway; but not before passing directly underneath us; with the difference in altitude showing only 200 ft. on my EFB (Electronic Flight Bag). Fortunately we were high; so we held our altitude until the other aircraft was able to turn away and landed without incident.
Flight Instructor reported a NMAC on short final with an aircraft landing on the parallel runway.
