magnetic stripes
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.

Answer:
Neurodegeneration
Explanation:
The term neurodegeneration refers to a group of disorders which are characterized by a progressive waste of function or structure of neurons, that in worst cases can include death of neaurons.
Many neurodegenerative disorders such as Parkinson's disease,– including amyotrophic lateral sclerosis, Huntington's disease and Alzheimer's disease can occur due to neurodegeneration.
Neurodegeneration can manifest itself in various forms such as lack of physical and intellectual abilities like inability to use muscles or memory loss. These disorders cannot be completely cured and ultimately lead to the death of neurons.
As mentioned in the question, the person suffers from progressive loss of intellectual and physical abilities that has occurred over the course of a long period of time. Therefore, it is most probable that he is having some neurodegenerative disorder.
