Answer:
The Correct Answer is D
Step-by-step explanation:
UN forces were commissioned to defend civilians after the division of Yugoslavia started a civil war and opened the nation into the struggle zone.
Despite the appearance of the UN troops and the making of UN-protected areas for civilians, Bosnian Serbs were able to catch almost 9000 Bosnian civilians which were later killed.
After this NATO forces came into the picture and took the initiative in determining further Bosnian Serbs moves.
