Beta globin is a globin protein, which along with alpha globin (HBA), makes up the most common form of haemoglobin in adult humans, the HbA. It is 146 amino acids long and has a molecular weight of 15,867 Da. Hb A (α2β2) is the major component of hemoglobin in normal adults, usually comprising about 97% of the total hemoglobin.
So, the correct answer is 'α2,β2.'
