I would say that D is the most important reason ie to monitor the location and magnitude of seismic activity to attempt to find patterns which may lead to the ability to predict the next earthquake in the world though individual seismic stations probably monitor more the seismic activity in their own country mostly though perhaps not exclusively.
If my memory serves me well, the answer should be: When the Congo River reaches Kinshasa, <span>it flows slowly into the Atlantic. Congo River is the second largest lake in the world. It takes a long way to reach the Atlantic: In the middle it flows towards Matadi and divides into several arms and finally it freely flows into the Atlantic.</span>
The Rainforest, because it has a lot of rain and is a very wet and humid climate which cause more types of vegetation to grow.
Hope this Helps!
