The correct answer is option 4, which is "More than 50%". This means that more than half of the world`s population lives in Asia.

Let`s break down the other options to better understand why they are not the correct answers:

Option 1: 30% - This option suggests that only 30% of the world`s population lives in Asia, which is lower than the correct answer of "more than 50%".

Option 2: 35% - Similar to option 1, this suggests a lower percentage than the correct answer. It implies that around one-third of the world`s population lives in Asia, but the correct answer is higher.

Option 3: 45% - This option suggests that nearly half of the world`s population lives in Asia. While this is closer to the correct answer, it is still below "more than 50%".

Therefore, the accurate answer is that more than half of the world`s population lives in Asia. It is important to note that the exact percentage may fluctuate over time due to population growth and migration trends.
