answer and explain

Assume that at time =0, both E and Y are at their long-run equilibrium levels. Next, assume that the domestic central bank temporarily decreases domestic money supply at =1. At t=2, the central bank completely reverses the policy. Finally, assume that the decrease in money supply is anticipated at =0. Noting that prices are fixed in the short-run, choose the correct option according to the DD-AA model: O A. There is no change in E and Y at =0. Both E and Y increase at t=1. At t=2, E and Y return to their original (t=0) values. O B. Both E and Y decrease at t=0. At t=1, E and Y decrease further. At t=2, E and Y increase to their t=0 values. O C. There is no change in E and Y at t=0, t=1 and t=2. O D. Both E and Y increase at t=0. At t=1, E and Y increase further. At t=2, E and Y decrease to their t=0 values. O E. There is no change in E and Y at 1=0. Both E and Y decrease at t=1. At t=2, E and Y return to their original (1=0) values
