According to the passage, which one of the following is critical in bringing quality in education?

Correct Option: Inculcating learning through activities and discovery

The passage highlights that bringing quality to education requires moving beyond rote learning and mere physical enrollment. It explicitly emphasizes active engagement of the learner and advocates for child-centric, discovery-based methods. This aligns perfectly with 'Inculcating learning through activities and discovery' (Option D). Ensuring physical attendance (Option A) or providing financial benefits to teachers (Option B) are structural or administrative measures but do not directly address the internal quality of the cognitive process. Understanding the socio-cultural background (Option C) is important but is not presented as the primary driver of educational quality. Therefore, Option D is the correct answer.
