The main aim of a social science teacher should be

Concept: Modern social science pedagogy (as reflected in the NCF and NCERT's position paper on Social Sciences) holds that the discipline exists to help learners see society as an interconnected whole — where geography, economy, history, and polity constantly shape one another — rather than as a set of isolated facts to be recalled or a set of rules to be obeyed without question.

Application: Applying this to the given aims, the one that matches this purpose is developing an awareness of the connections between all the elements that shape society: it asks the teacher to help learners trace how, say, a region's geography affects its economic activity, and how that economic activity in turn shapes its political and social structures — building integrated, critical understanding rather than surface exposure.

Cross-check — why each of the other stated aims fails:

• Fostering competition among students is a classroom-management technique aimed at motivation, not a disciplinary aim of social science — it says nothing about what learners should come to understand.

• Making learners memorize socio-historical facts reduces the subject to rote recall, which is exactly what integrated social science teaching is meant to move beyond.

• Preparing learners to maintain the status quo and accept every government decision promotes passive conformity, whereas social science education is meant to build informed, questioning citizens who can evaluate society critically.

Result: Given this, the aim of building learners' awareness of the connections among the geographic, economic, historical, and political elements that shape society reflects an integrated, critical view of social science education, consistent with the CTET (Paper 2, 2019) syllabus objectives for the subject.
