B) Africa

Africa is often referred to as the "ocean of the continent" due to its vast coastline and the presence of several major bodies of water surrounding it. It is the second-largest continent in the world and is located primarily in the Eastern Hemisphere.

Key Points:

1. Vast Coastline: Africa has a coastline that stretches for approximately 30,490 kilometers (18,950 miles), making it the continent with the third-longest coastline after Asia and North America. This extensive coastline is home to numerous coastal countries, including Morocco, Egypt, Nigeria, South Africa, and many more.

2. Major Bodies of Water: Africa is surrounded by several major bodies of water, including the Atlantic Ocean to the west, the Indian Ocean to the east, and the Mediterranean Sea to the north. These bodies of water not only provide important trade routes and fishing grounds but also influence the climate and weather patterns of the continent.

3. Important Waterways: Africa is also home to several significant waterways, such as the Nile River, which is the longest river in the world, and the Congo River, which is the second-largest river in terms of discharge volume. These rivers play a crucial role in providing water for irrigation, transportation, and supporting diverse ecosystems.

4. Biodiversity: The surrounding oceans and seas of Africa are home to a rich variety of marine life, including numerous species of fish, mammals, and marine plants. The coastal regions of Africa support important ecosystems such as coral reefs, mangroves, and seagrass beds, which are vital for the overall health of the oceans and the sustainability of marine resources.

In conclusion, Africa is often referred to as the "ocean of the continent" due to its vast coastline, the presence of major bodies of water surrounding it, and the rich biodiversity found in its marine ecosystems.
