Hope this answers the question. Have a nice day.
The correct asnwer is C because we all know that the Nile River is by egypt
Answer:
- May be it was formed by faulting using the compression forces and hence formed due to the reverse faults formed
- Or, it was formed due to downwarping
Anyways it would have been better if you added the picture of the valley
