Human Factors
I was conducting a training flight with a student pilot. I was teaching how to stay on glide path for landing; and how to correct when the airplane is high or low. This time we came in low; another aircraft noticed and mentioned to Tower that they thought we were too low; ZZZ Tower told the other aircraft 'They're fine'. Which we were; we had ample clearance over the obstacles at the end of Runway XXR approach. Had we gotten to an unsafe altitude I as acting PIC was ready to take the controls and execute a go-around maneuver.
Flight Instructor reported that another Pilot reported their aircraft to ATC as being too low for safe flight. The tower controller stated that was not the case and the Instructor continued the approach to landing.
