The following reaction shows the products when sulfuric acid and aluminum
hydroxide react.
2Al(OH)3 + 3H2SO4 → Al2(SO4)3 + 6H20
The table shows the calculated amounts of reactants and products when the reaction
was conducted in a laboratory.

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.
