Answer: d. Europe
Step-by-step explanation:
Asia is the largest of all seven continents with its total area being around 44.58 million km². Europe on the other hand, is the 6th largest continent, only larger than Oceania in area as it covers around 10.18 million km² of the earth's surface area.
Europe can therefore fit almost 4.5 times into Asia when their land masses are compared:
= 44.58 / 10.18
= 4.4 times
