b.Africa
c.Europe
d.Sout

Hint: A continent is a large mass of land which is regarded as a collective region. There are seven continents: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.

Complete Step by Step Answer: The continents are not distributed uniformly over the Earth's surface. More than two-thirds of the Earth’s surface lies towards the north of the Equator. The continent is mainly made up of metamorphic and igneous rock, largely of granitic composition.

The total land area covered by the continents is 148,647,000 square kilometres which are 29.1% of earth's surface. The rest 71% is covered by water.

The smallest continent is Australia and the largest one in Africa.

Looking at the options above:

Option a: Asia covers 44,579,000 square kilometres. This is an incorrect option.

Option b: Africa is the largest continent covering 30,370,000 square kilometres of land. This is the correct option.

Option c: Europe covers about 10,180,000 square kilometres of land area. This is an incorrect option.

Option d: South America covers about 17,840,0000 square kilometres of land area. This is also an incorrect option.

Option 'b' is correct.

Note: While answering this question don't get confused between Asia and Africa. Asia is the most populous continent but Africa is the largest continent in terms of area.
