A smart classroom is an ICT supported classroom, one equipped with digital tools such as projectors, computers and internet access.

It integrates information and communication technology into ordinary teaching to enrich content delivery.

A teacher-centric classroom (option A) is defined by teacher control, not by technology, so it is a different concept.

A flipped and blended classroom (option C) is a specific method of organizing learning, not the definition of a smart classroom.

A learner-centric classroom (option D) describes who is at the centre, again not the same as being ICT equipped.

ICT integration in education is promoted in India through initiatives like SWAYAM and the National Digital Library.
