`AgNO_(3(aq))+Na_2S_((aq)) rarr Ag_2S_((s))+NaNO_(3(aq))`
`Ag_2S ` is a black coloured solid.
`AgNO_(3(aq))+K_2CrO_(4(aq)) rarr Ag_2CrO_(4(s))+KNO_(3(aq))`
`Ag_2CrO_4` is a brown-red coloured solid.
`NiCl_(2(aq))+NaOH_((aq)) rarr Ni(OH)_(2(aq))+NaCl_((aq))`
`Ni(OH)_2` is a green colour solid
`CuSO_(4(aq))+NH_(3(aq)) rarr Cu(OH)_(2(aq))+(NH_4)_2SO_(4(aq))`
`Cu(OH))_2` is blue colour solid.
So the red precipitate forms by `AgNO_3 + K_2CrO_4` mixture. The correct answer is (B)
