Correct option is D
Both Assertion (A) and Reason (R) are false. A progressive classroom environment is characterized by its encouragement of open discussion, critical thinking, and a respect for diverse opinions rather than maintaining 'pin-drop' silence. The role of the teacher in such a setting is more of a facilitator than a didactic authority figure. Moreover, the notion that children learn only when teachers exercise total control is a misconception. Effective learning occurs in an environment where students are encouraged to explore, question, and engage actively in their learning process.
