C) Al(s)+3Ag^+(aq)--->Al^3+(aq)+3Ag(s) D) All of the above
 
Answer & Explanation Answer: D) All of the above

Explanation:

A redox reaction is a type of reaction which involves transfer of electrons among two species. This reaction is also called oxidation-reduction reaction.

In oxidation process, there is an increase in oxidation state of an atom, ion or molecule by losing the electrons.

In reduction process, there is a decrease in oxidation state of an atom, ion or molecule by accepting the electrons.
