Which national team won the 2015 Mens Rugby World Cup final?

Introduction / Context:
Earlier we saw a question about the host country of the 2015 Mens Rugby World Cup. This question now checks whether you remember which national team actually won the tournament. Separating the champion from the host is an important detail in sports general knowledge.

Given Data / Assumptions:
The question gives the following information.

• The event is the 2015 Mens Rugby World Cup.
• We must identify the winning national team.
• Options include New Zealand, Australia, South Africa and England.

Concept / Approach:
The 2015 Rugby World Cup final was played between New Zealand and Australia at Twickenham Stadium in England. New Zealand, also known as the All Blacks, delivered a strong performance and defeated Australia in the final. This win made New Zealand the first team to win three Rugby World Cups and the first to retain the title after winning in 2011. Therefore, the correct answer is New Zealand, not the host country England or the other rugby powers in the list.

Step-by-Step Solution:
Step 1: Recall that the final of the 2015 Rugby World Cup was contested by New Zealand and Australia. Step 2: Remember that England, the host, did not reach the final and was eliminated earlier in the tournament. Step 3: Recall that New Zealand beat Australia in the final with a comfortable score margin. Step 4: Compare this with the options and identify New Zealand as the champion team. Step 5: Select New Zealand as the correct answer.

Verification / Alternative check:
You can verify by thinking about the All Blacks record. New Zealand won Rugby World Cups in 1987, 2011 and 2015. Many articles highlighted that they became the first team to win back to back titles with the 2015 victory. This strong media coverage provides a reliable memory anchor that confirms New Zealand as the winner in 2015.

Why Other Options Are Wrong:
Option B Australia is wrong because although Australia reached the final, it finished as runner up to New Zealand. Option C South Africa is incorrect because South Africa won earlier editions such as 1995 and 2007, not the 2015 tournament. Option D England is wrong as England was the host country, not the champion, and was eliminated in the pool stage.

Common Pitfalls:
Candidates sometimes mix up winner and host or recall only that Australia played in the final and accidentally pick Australia as champion. Keeping a timeline of Rugby World Cup winners along with hosts can prevent such confusion. Remember that in 2011 and 2015 the champion was New Zealand, while the host countries were New Zealand and England respectively.

Final Answer:
The 2015 Mens Rugby World Cup was won by New Zealand.
