A The diagrams both provide support for he theory that the continents have always been fixed in their current positions.
b
The diagrams have little relationship to each other, as some of the land areas shown on the diagrams are in different positions.
c
The diagrams support each other by offering two separate sources of evidence that support the past shapes and positions of the landforms.
d
The diagrams provide support for the conclusion that the process of continental drift ended when the continents reached their current positions.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
