The correct option is D.
Cu2+ being reduced.
Reduction is gain of electrons. Oxidation is loss of electrons.
Cu2+ is reduced to Cu. Fe is oxidised to Fe3+ .
Fe is a reducing agent, because it causes the Cu2+ to be reduced Cu and Cu(NO3)2 is a oxdising agent because it causes the Fe to be oxidised to Fe3+.
