Crystalline Solid

Explanation:

Rock, sand, metals, salts, etc. are some examples of polycrystalline solids. It is the opposite extreme of a single crystal. These types of solids have neither reticular nor granular structure

  Crystalline solid

Explanation:  Crystalline solids are those in which the constituents are arranged in the systematic order. These constituents are held together by the strong forces of attraction.

There is a regular pattern of the molecules which is repeated uniformly through the crystal lattice.

Thus when salt is being examined under microscope, then these similar pattern would have been retrived. Thus the magnified image of the salt can be best described as the crystalline solid.

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.
