To achieve this, (B) the government fixes the exchange rate higher than the market rate (meaning more domestic currency per dollar, making domestic currency cheaper and exports competitive). This policy leads to (D) increased export earnings causing supply of dollars to exceed demand. Finally, (A) the central bank intervenes by purchasing the excess dollars to maintain the fixed exchange rate and prevent it from falling below the desired level. This sequence demonstrates how fixed exchange rate regimes require active central bank intervention to maintain the peg. -> correct
