As per NCF 2005, good Science education should be

NCF 2005 (National Curriculum Framework, 2005) laid down three guiding criteria that any good science curriculum and teaching must satisfy: it must be true to the child, true to life, and true to science.

• True to the child: it must engage the learner's own experience, curiosity, and stage of cognitive development, not just transmit ready-made facts.

• True to life: it must connect scientific ideas to the learner's environment and lived experience.

• True to science: it must reflect the actual nature and methods of scientific inquiry, not reduce science to rote content.

Among the given options, only "true to the child" names one of these three criteria the way NCF 2005 itself states it.

Contrasting the other options: "true to science teacher" inverts the child-centred shift NCF calls for by centring the teacher instead of the learner; "true to the environment of the school" and "true to the classroom culture" both narrow the framework's broader idea of the learner's context to one specific institutional setting, which is not how NCF phrases its criteria.

So, as per NCF 2005, good science education should be true to the child.
