(C) The iron atom in the haemoglobin of blood is in the $+2$ oxidation state,i.e.,iron is present as $Fe^{2+}$.$Mg^{2+}$ is the central atom of the chlorophyll molecule,which is essential for photosynthesis.Cobalt is an essential trace element for humans and is found at the centre of vitamin $B_{12}$ and a range of other co-enzymes called cobalamins.There is no involvement of $Se^{2+}$ in the Kreb cycle.Thus,the wrong combination is $C$.
