According to standard electrode potential,which is the strongest reducing agent and oxidising agent?
$Al (-1.66 \ V), Cu (+0.34 \ V), Li (-3.05 \ V), Ag (+0.80 \ V)$

• A
  Strongest reducing agent: $Li$,Strongest oxidising agent: $Ag^{+}$
• B
  Strongest reducing agent: $Al$,Strongest oxidising agent: $Cu^{2+}$
• C
  Strongest reducing agent: $Ag$,Strongest oxidising agent: $Li^{+}$
• D
  Strongest reducing agent: $Cu$,Strongest oxidising agent: $Al^{3+}$
