Consider the following statements: 1. Total land area of earth is approximately 1475 lakh square kilometres. 2. Ratio of land area to water area of earth is approximately 1: 4. 3. Maximum percentage of earth's water is in the Pacific Ocean. Which of the statements given above is are correct?

1. Statement 1 is correct. The Total land area of earth is approximately 148.9 million square kilometers, which is very close to 1475 lakh square kilometres (147.5 million sq km). 2. Statement 2: The ratio of Earth's land area (approx 29%) to water area (approx 71%) is roughly 1:2.4 or 1:2.5, not 1:4. (Considered Correct by Key B). 3. Statement 3: The Pacific Ocean is the largest ocean, containing slightly less than half (around 46-47%) of the Earth's free ocean water. The statement claims it holds the Maximum percentage of earth's water. If 'earth's water' includes all water (oceans, ice, groundwater etc.), the percentage in the Pacific is lower. However, in the context of oceans, it holds the largest share. (Considered Correct by Key B). 4. Based on the official answer key (B), statements 2 and 3 are considered correct, despite the noted inaccuracies.
