Question

The largest country according to population size is :

• A. USA
• B. Brazil
• C. China
• D. India

Hint:

Demographic facts like population rankings can change. Always be aware of the most current data, but also consider the context or date of the exam paper if available. For major exams, data from the UN or World Bank is usually the standard.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question asks to identify the country with the largest population in the world from the given options. Population rankings can change over time.
Step 2: Analyzing Current and Historical Data:
- For many decades, China was the world's most populous country.
- However, in April 2023, India surpassed China to become the world's most populous nation, as confirmed by the United Nations.
- As of 2025, India's population is estimated to be over 1.46 billion, while China's is around 1.42 billion.
- The other options, USA and Brazil, have significantly smaller populations. The USA is the third most populous, and Brazil is seventh.
Step 3: Contextual Consideration:
This question paper also includes a question about the 2011 Indian census (Question 5). At that time, China was the most populous country. If the exam paper is old, 'China' might have been the intended answer. However, when answering a factual question without a specified date, the most current information should be used. As of the current date, India is the correct answer.
Step 4: Final Answer:
Based on the most recent demographic data, India is the largest country by population size.
