Step-by-step explanation:
When Kevin Rudd became Australian Prime Minister in 2007, he issued a formal apology to Indigenous Australians (Option A). The apology addressed past injustices committed against this group, including the forced removal of Indigenous children from their families, a practice that became known as the Stolen Generations. The Australian government had long been criticized for these historical actions and the mistreatment of Indigenous people, and Rudd's apology was a significant moment in Australian history aimed at reconciliation.
