Which national team won the inaugural ICC T20 Cricket World Cup (ICC World Twenty20) tournament?

Introduction / Context:
The ICC T20 Cricket World Cup, earlier called the ICC World Twenty20, marked the arrival of Twenty20 cricket as a major international format. The result of the first edition is a popular question in sports general knowledge because it introduced a new world champion in a shorter, more explosive style of cricket. This question asks which national side won that very first T20 World Cup.

Given Data / Assumptions:

• The tournament is the first ICC T20 World Cup (World Twenty20).
• It was played in South Africa in 2007.
• Options list India, West Indies, Australia, New Zealand, and Pakistan.
• We assume standard ICC match records.

Concept / Approach:
The inaugural ICC World Twenty20 was held in 2007. India, under captain Mahendra Singh Dhoni, won the tournament by defeating Pakistan in a dramatic final at Johannesburg. This victory is remembered for close finishes, the introduction of the bowl out earlier in the tournament, and the emergence of young Indian players in the T20 format. Therefore, India is the correct answer, while the West Indies titles came in later years.

Step-by-Step Solution:
Step 1: Recall that the first ICC T20 World Cup took place in 2007 in South Africa.Step 2: Remember that the final was contested between India and Pakistan.Step 3: Recall that India defended a modest total and won a tense match when Misbah ul Haq was caught attempting a scoop shot.Step 4: Confirm that this victory gave India the first ICC World Twenty20 title.Step 5: Choose India from the given options.

Verification / Alternative check:
You can verify this by thinking of how the Indian Premier League (IPL) started soon after India's 2007 T20 World Cup win. The success of that Indian team made T20 cricket extremely popular in India, which in turn helped launch the IPL in 2008. This strong link between India's title and the birth of franchise T20 leagues reinforces the memory that India won the first T20 World Cup.

Why Other Options Are Wrong:
The West Indies won T20 World Cups later, not the inaugural one. Australia has been successful in many formats but did not win the 2007 T20 World Cup. New Zealand is a strong limited overs team but did not reach the final of that first edition. Pakistan reached the final in 2007 but lost to India, so it cannot be the champion in this specific tournament.

Common Pitfalls:
Candidates sometimes confuse different ICC tournaments and may think of the ODI World Cup winners instead of the T20 winners. Others may recall that West Indies are multiple T20 World Cup champions and mistakenly assume they won the first one. Paying attention to the year 2007 and the venue South Africa helps anchor the fact that India lifted the inaugural title.

Final Answer:
The inaugural ICC T20 Cricket World Cup was won by India.
