Which one of the following countries was the winner of FIFA confederations cup 2017?

The answer is Germany. The 2017 FIFA Confederations Cup was held in Russia as a warm-up for the 2018 World Cup, and Germany beat Chile in the final to lift the trophy. Germany had also won the 2005 edition, so this was their second title.

• Chile (A): Chile were the runners-up in 2017. They were a strong side, having won the Copa America in 2015 and 2016, but they lost the final to Germany.
• Mexico (C): Mexico's only Confederations Cup title came as hosts in 1999. They did not win in 2017.
• Portugal (D): Portugal were the reigning European champions after Euro 2016, but they did not reach the final in 2017.

The core concept is simply the list of FIFA tournament winners, which UPPSC often tests through sports-current-affairs items. For Mains, the link is to how such events function as the recognised continental-champion tournaments that feed into FIFA's global calendar.

Trap: Candidates confuse the Confederations Cup with the Copa America or Euro, or assume the reigning European champion Portugal must have won.
