Which or the following is a rift valley?

Solution (By Examveda Team)

The Rhine is a rift valley. The Rhine Rift valley shape is the result of the rifting which begins some 60 million years ago. It is known as a hot spot due to the eruption of the hot mantle into the crust, which caused the crust uplift and the mantle overflow with the development of the Black Forest, the Vosges and the Rhine Rift valley.
