Which one of the following is the correct sequence of the given Continents in the decreasing order of their percentage of earth’s land?

Standard rankings of continents by land area place them (largest to smallest) as Asia, Africa, North America, South America, Antarctica, Europe and Australia; thus among the four continents named, Africa is largest, followed by North America, then South America, with Europe the smallest of the four [1]. Contemporary sources also note Africa’s vast extent — about 30.3 million km² — which far exceeds the area of North America, South America and Europe, underscoring the correct descending order as Africa → North America → South America → Europe [2]. Therefore option 2 correctly lists the continents in decreasing order of their share of Earth’s land.
