Which quality of a human teacher becomes important against the rigidity of the mechanical teacher?

Flexibility

The governing concept is adaptability in teaching. A mechanical teacher follows programmed rules and may continue in the same manner even when a child has not understood. A human teacher can recognise different abilities, difficulties, moods, and learning speeds, then change the explanation, example, activity, or pace. This quality is flexibility, so option A is correct. Option B describes a possible physical construction, not a teaching strength. Option C concerns the display, and option D suggests fixed behaviour; neither helps a teacher respond to individual needs. The story’s contrast implies that technology can deliver information efficiently, but human guidance is valuable because it can interpret a child’s response and adjust instruction accordingly.
