The oxygen–hemoglobin dissociation curve describes the percent oxygen saturation of hemoglobin as a function of the partial pressure of oxygen (PO2) in the surrounding fluid. As the PO2 increases on the horizontal axis, the oxygen saturation percentage also increases on the vertical axis. In comparison to that of adult hemoglobin, how is the fetal oxygen–hemoglobin dissociation curve shifted?

a. to the left of the adult curve, indicating a lower oxygen affinity of fetal hemoglobin
b. to the left of the adult curve, indicating a higher oxygen affinity of fetal hemoglobin
c. to the right of the adult curve, indicating a lower oxygen affinity of fetal hemoglobin
d. to the right of the adult curve, indicating a higher oxygen affinity of fetal hemoglobin
