The River Nile is a river in northeastern Africa and is the longest river in the world, though some sources cite the Amazon River as the longest.

In particular, the Nile is the primary water source of Egypt and Sudan.

The verb "flow" is used to describe the movement of a liquid, such as water. In the sentence "The River Nile flows into the Mediterranean," the verb "flows" is used to describe the movement of the Nile River from its source in the East African Rift Valley to its mouth on the Mediterranean Sea.
The other options are incorrect because they do not accurately describe the movement of the Nile River. Option A, "is flowing," is incorrect because it implies that the Nile River is currently in the process of flowing. However, the Nile River is a continuous body of water, and it is always flowing. Option B, "has flown," is incorrect because it implies that the Nile River has stopped flowing. However, the Nile River is always flowing. Option D, "will be flowing," is incorrect because it implies that the Nile River will start flowing in the future. However, the Nile River is always flowing.
