In the Copa America football championship 2016 final, which national team did Chile defeat to win the title?

Introduction / Context:
The Copa America is the main international football tournament for national teams in South America. In the 2016 edition, often called Copa America Centenario, Chile won the title by defeating a major rival in the final. This question checks your memory of that high profile match.

Given Data / Assumptions:

• The tournament is Copa America 2016.
• Chile emerged as champions.
• The question asks which national team Chile defeated in the final.
• Options include Colombia, Argentina, Ecuador and Peru.

Concept / Approach:
Chile and Argentina met in back to back Copa America finals in 2015 and 2016. In both cases the matches were decided on penalties and Chile lifted the trophy. The approach here is to recall that Chile victory in 2016 also came against Argentina, led by Lionel Messi, rather than against Colombia, Ecuador or Peru.

Step-by-Step Solution:
Step 1: Recall the finalists in Copa America 2016, played in the United States as a special centenary edition.Step 2: Remember that Chile and Argentina faced each other in the final, repeating the matchup from the previous year.Step 3: The match ended goalless after normal and extra time and was decided by a penalty shootout, where Chile prevailed.Step 4: Compare this with the options given. Colombia, Ecuador and Peru all participated in the tournament but did not contest the final against Chile.Step 5: Therefore, the correct answer is Argentina.

Verification / Alternative check:
To verify, you can recall the dramatic images of Lionel Messi missing a penalty in the shootout and later announcing a temporary retirement from international football, which was widely reported. That moment was directly linked to Argentina loss in the final to Chile. Colombia participated in the third place match, and Ecuador and Peru exited earlier. This strongly supports Argentina as the correct opponent.

Why Other Options Are Wrong:
Option A, Colombia, finished third and did not face Chile in the final. Option C, Ecuador, and option D, Peru, were eliminated before the last match and did not reach the title game. While they are legitimate South American teams, they are not the side that Chile defeated for the 2016 Copa America crown.

Common Pitfalls:
Learners sometimes mix up different editions of Copa America or confuse semifinal and third place opponents with finalists. Another pitfall is to remember that Messi and Argentina lost to Chile in a final but not be sure whether it was in 2015 or 2016. The key is to remember that both finals in these two consecutive years featured the same matchup, and Chile beat Argentina again in 2016.

Final Answer:
In the Copa America 2016 final, Chile defeated Argentina to win the title.
