Answer:
A. Congo River
Explanation:
The Congo or Zaire River is one of the longest and fastest rivers on the planet. It bathes equatorial Africa and flows into the Atlantic Ocean. The Congo river regime is characterized by regularity, as the drought months of the southern hemisphere tributaries (Ruki and Kasai) are offset by the floods of the northern hemisphere tributaries (Ubangui) and vice versa. Congo is one of the major communication routes of equatorial Africa. From Kisangani to the mouth, this river and its tributaries offer a navigable network of approximately 14,500km.
