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 permanently increases domestic money supply at t=2. Finally, assume that the increase in money supply is anticipated at t=1. Assuming 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 t=1. Both E and Y increase at t=2. O B. Both E and Y increase at t=1. There is no change in E and Y at t=2 O C. Both E and Y increase at t=1. Only Y increases at t=2 O D. Both E and Y increase at t=1. At t=2, E and Y increase further O E. Both E and Y increase at t=1. Only E increases at t=2
