Which among the following countries has the largest population?

Among the four countries listed, Indonesia has the largest population. United data compilations place Indonesia well above the others — for example, a recent country-by-country population table lists Indonesia at about 285.7 million, Pakistan at about 255.2 million, Japan around 123.1 million, and Sudan near 51.7 million, making Indonesia clearly the most populous of the four. These rankings are corroborated by World Bank population tables for 2022, which also rank Indonesia above Pakistan and Japan in total population, confirming Indonesia as the largest among the given options [1].
