Answer:
The correct answer is A. The 2008 presidential election was the first time that an African American was elected president of the United States.
Step-by-step explanation:
The 2008 presidential elections took place on November 4th and, as usual, were anticipated by almost two years of electoral campaign and by primaries for the selection of candidates. The challenge was countered by the Republican candidate John McCain and the democratic candidate Barack Obama, who finally won the election. On January 20, 2009, Obama, the first African-American to be elected head of the country, was sworn in as the 44th president of the United States and took office.
