As per NCF-2005, good science education should be A. True to the learner B. True to the environment of the learner C. True to the teacher D. True to science

According to NCF-2005, good science education should be true to the child/learner (developmentally appropriate), true to the environment of the learner (contextual and relevant to local conditions), and true to science (scientifically accurate and reflecting the true nature of science). It is not specifically defined as 'true to the teacher.' Hence A, B, and D are the correct criteria.
