Explanation:
The evidence that supports the proposition that sea floor spreading occurs from the options are the magnetic stripes and molten materials.
Harry Hess proposed the concept of sea floor spreading which further led to the development of the theory of plate tectonics.
Some of the evidences used are :
- Magnetic stripes in the rocks of the oceanic crust around spreading centers.
- They were discovered using magnetic survey of the ocean floor.
- Bands of magnetic minerals were seen to be oriented in particular direction and forms different patterns in the rock.
- Also, along spreading centers, molten materials rich in basalt abounds.
- This is because when sea floor begins to move apart, magma upwells from deep within the asthenosphere to replace them.
