As of the end of the ICC Cricket World Cup 2015, which of the following national teams had never won the Cricket World Cup title?

Introduction / Context:
The ICC Cricket World Cup is the premier international tournament in One Day International cricket, and exam questions often focus on which teams have won the title and which have not at certain points in history. This question is carefully time bound: it specifically mentions the situation as of the end of the ICC Cricket World Cup 2015. Several strong cricket playing nations had still not lifted the trophy by that time. You must identify which among the given teams had never won the World Cup up to and including the 2015 edition.

Given Data / Assumptions:

• The reference point is the end of the ICC Cricket World Cup 2015.
• The teams listed are Bangladesh, England, and South Africa.
• We must determine which of these had never won a World Cup title by that time.
• The option All of the above suggests that possibly all three had not yet been champions.

Concept / Approach:
The concept is historical sports knowledge with careful attention to time. Prior to 2015, World Cup winners included West Indies, India, Australia, Pakistan, Sri Lanka, and again India and Australia in later editions. By 2015, neither Bangladesh, nor England, nor South Africa had won a World Cup. England, despite being the birthplace of modern cricket, only became world champions later. South Africa has often been called a strong team that struggles in World Cups, and Bangladesh has been an emerging side. Thus, the correct approach is to list all winners up to 2015 and then check which of the teams in the options are missing from that list.

Step-by-Step Solution:
Step 1: List the World Cup winning teams up to 2015: West Indies, India, Australia, Pakistan, and Sri Lanka. Step 2: Check whether Bangladesh appears in that winners list. It does not, so Bangladesh had never won the title by 2015. Step 3: Check whether England appears in that winners list. Up to 2015, England had reached finals but had not won the trophy. Step 4: Check whether South Africa appears in that winners list. South Africa had also not won any World Cup title by 2015. Step 5: Since all three listed teams are missing from the champions list up to 2015, choose All of the above.

Verification / Alternative check:
Verification can be done by recalling specific tournament stories. England lost World Cup finals in earlier years but were still searching for their first title before 2019. South Africa gained a reputation for unlucky exits in knockout stages and group matches, which is frequently referenced in cricket discussions. Bangladesh has progressed steadily but was nowhere near a title win by 2015. If you remember that the 2015 final was between Australia and New Zealand, with Australia winning yet another title, it confirms that none of the three listed teams had become champions by that point.

Why Other Options Are Wrong:
Bangladesh: This team had not won a World Cup by 2015, which is true, but choosing only Bangladesh ignores the fact that England and South Africa were also without titles, so option A alone is incomplete.
England: England had not won a World Cup by 2015, but this fact is shared with Bangladesh and South Africa, therefore choosing only England is also incomplete.
South Africa: South Africa was also without a World Cup title by 2015, but again it is not the only team in that situation, so option C alone is incorrect.

Common Pitfalls:
Learners sometimes forget the time reference and answer based on the latest information rather than as of 2015. For example, after England later won a World Cup, some candidates misapply that fact to earlier years. Another pitfall is to remember only one or two teams that have not won and to ignore the broader pattern. Always pay attention to the year mentioned in the question and check all options against the complete list of champions up to that year. This disciplined approach avoids errors in time bound sports questions.

Final Answer:
As of the end of the ICC Cricket World Cup 2015, none of Bangladesh, England, or South Africa had won the Cricket World Cup, so the correct option is All of the above (option D).
