The affinity that hemoglobin has on oxygen is decreased when the pH of the solution is decreased. When the solution is at a lower pH, hemoglobin tends to release more oxygen because it doesn't have as much affinity to keep the oxygen binded to the heme group. A more active tissue will be producing more heat and will be warmer. This increased temperature may lead to changes in hemoglobin's affinity to oxygen in a similar fashion as would be expected from a decrease in pH.
SO ANSWER WOULD BE B) DECREASE
