None of the above options are correct. The red color of oxyhaemoglobin is due to the absorption of light in the visible spectrum by the heme group, which consists of a porphyrin ring complexed with an iron ion. Specifically, the red color is due to the Soret band, which arises from a d-d transition within the iron ion.

There is no option mentioned for "intra ligand" in the question. The correct answer is a) d-d transition. Oxyhaemoglobin contains iron (Fe) in its heme group, which undergoes a d-d transition upon binding oxygen. This transition results in the absorption and reflection of light in the red part of the spectrum, giving oxyhaemoglobin its characteristic red color.
