B Correct answer
Explanation

Oceans cover approximately 71% of Earth's surface, though 75% is commonly used as a rounded figure in educational materials. 98% would leave almost no land, 80% is too high, and 50% would mean equal land and water coverage - none of these match the actual distribution.
