How did an increase in consumer confidence change the final equilibrium point of the expansionary policy as shown in this graph?

a. Instead of reaching the target of E3 and at RGDP3, the final result is E4 at RGDPNR.

b. Instead of reaching the target of E2 and at RGDPNR, the final result is E4 at RGDPNR.

c. Instead of reaching the target of E2 and at RGDPNR, the final result is E3 at RGDP3.

d. Instead of reaching the target of E3 and at RGDP3, the final result is E1 at RGDP1.

b. Instead of reaching the target of E2 and at RGDPNR, the final result is E4 at RGDPNR.
