Step-by-step explanation:
Among the options given, social justice reforms are most likely to win a modern leader a reputation for greatness.
While economic prosperity, military conquests, and technological advancements can certainly contribute to a leader's reputation, social justice reforms address fundamental issues of equity and equality in society. They aim to create a more just and fair society by addressing issues such as poverty, discrimination, and human rights. Leaders who champion social justice reforms are often seen as progressive, compassionate, and committed to improving the lives of their citizens.
An example of a modern leader who achieved a reputation for greatness through social justice reforms is Nelson Mandela. As President of South Africa, Mandela fought against apartheid and advocated for racial reconciliation, social equality, and human rights. His efforts in promoting social justice not only earned him international recognition but also helped transform South Africa into a more inclusive and equal society.
