Which country won FIFA World Cup 2010?

The FIFA World Cup 2010 was a historic tournament held in South Africa. The foundational concept here is knowledge of major international sporting event outcomes. Spain emerged as the champions, defeating the Netherlands 1-0 in the final match with an extra-time goal by Andrés Iniesta. This marked Spain's first-ever World Cup title, solidifying their golden era in international football.

• Brazil was eliminated in the quarter-finals by the Netherlands.
• Argentina also exited in the quarter-finals after a heavy defeat to Germany.
• Germany finished third in the tournament, beating Uruguay in the third-place playoff.

These nations are strong footballing powers, but they did not secure the championship in 2010, making Spain the accurate answer.
