Concept:
The Earth's landmass is divided into seven major geographic continents. Analyzing them requires arranging them systematically in descending order of their physical area.
Step 1:
Let us review the standard ranking of all world continents by surface area:
• Asia (Largest continent)
• Africa (Second-largest continent)
• North America
• South America
• Antarctica
• Europe
• Australia (Smallest continent)
Step 2:
The question specifically asks for the world's *second largest* continent. According to geographical measurements, Africa covers an area of about 30.3 million square kilometers, making up approximately 20% of the planet's total land area. Therefore, Option (B) is the accurate answer.
