In a second experiment, the isolated splenic and lamina propria macrophages were treated with LPS and then incubated with the protein antigen, chicken ovalbumin. CD4 T cells specific for a peptide of ovalbumin (OVA) bound to MHC class II were then incubated with each population of macrophages, and three days later, the culture supernatants were analyzed for IL-2 and IFN-$\gamma$ production. Which of the graphs in Figure most likely represents the results of this experiment?
