In an aqueous solution ferric ion  gives blood red colour with potassium thiocyanate solution. Which of the following gives blood red colour with KSCN solution 

${\mathrm{Fe}}_4{\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]}_3\underset{ }{\rightleftharpoons }4{\mathrm{Fe}}^{+3}+3{\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]}^{-4}$

This solution contains free ${\mathrm{Fe}}^{+3}$ ion
(2) & (4) --${\mathrm{Fe}}^{+3}$ ion is in complex ion ….It cannot react with ${\mathrm{SCN}}^{–}$ ion
(3) Does’nt contain ${\mathrm{Fe}}^{+3}$ ion
