Answer:
The correct answer is B. The Presidential Election of 2008 was the first time that an African-American was elected as President of the United States.
Step-by-step explanation:
On November 4, 2008, Barack Obama won the presidential elections in the United States, becoming the first African-American president in the history of the country, by winning by a wide margin against his rival, Republican John McCain.
These elections were characterized by the massive influx of voters, and the climate of enthusiasm and commitment that existed in the country.
Obama succeeded George W. Bush as head of the White House, transmitting a message of change, unity, prosperity and the promotion of peace. He was awarded with the Nobel Peace Prize in 2009 "for his extraordinary efforts in strengthening international diplomacy and cooperation among peoples."
In 2012 he was re-elected president in front of Mitt Romney, in what meant his second consecutive term.
