Which geographic feature is Africa's easternmost peninsula?

• A. Horn of Africa
• B. Sinai Peninsula
• C. Cape of Good Hope
• D. Arabian Peninsula

Answer: (A)

When we look at Africa’s edge in terms of longitude, the feature that stretches furthest to the east is the Horn of Africa. This eastern projection, including Somalia and nearby regions, reaches into the Indian Ocean with Cape Guardafui at its tip, farther east than any other African peninsula.

The Sinai Peninsula is farther north and often considered part of Asia, so even though it is a prominent peninsula, it does not extend as far east as the Horn. The Cape of Good Hope sits at the southern tip of Africa, not the east. The Arabian Peninsula lies across the Red Sea and is a separate landmass, not part of Africa. So the Horn of Africa is Africa’s easternmost peninsula.
