The objective of discussing 'equality' in a social science classroom is to A.…

A classroom discussion on a value such as equality is meant to build the underlying values and behaviour students should carry -- respecting others, upholding dignity, and honouring constitutional principles -- not to make a claim about how differences among people work. Recognising that people differ is compatible with equality; noticing a difference does not, by itself, create inequality.

Checking each proposed statement: addressing issues of dignity with the learners, and sensitizing learners towards respecting everyone, are both core aims of an equality discussion, and building upon values enshrined in the Constitution reflects the constitutional basis of equality (the Right to Equality). The remaining statement -- that all differences lead to inequality -- inverts the actual teaching goal: differences in ability, background, or identity do not inherently cause inequality; treating people fairly despite those differences is what equality means.

• The set that keeps the dignity aim and the respect aim also keeps the differences-cause-inequality claim, which contradicts the constitutional message of fair treatment despite difference.

• The set that keeps the dignity aim and the constitutional-values aim also keeps the differences-cause-inequality claim, which again contradicts that same constitutional message.

• The set that keeps the respect aim and the constitutional-values aim also keeps the differences-cause-inequality claim, repeating the same contradiction.

Every set that keeps the differences-cause-inequality claim contradicts the constitutional idea that people are to be treated fairly regardless of difference, so none of those sets can describe the objective. Only the set built from the dignity aim, the respect aim, and the constitutional-values aim -- without the differences-cause-inequality claim -- consistently describes the objective of discussing equality in a social science classroom.
