Answer:
B) Controlling the interest rate in the country and imposing restrictions on foreign exchange trading.
Explanation:
To ensure stability in international trade and investment, Iraq must keep a stable interest rate, so that investors can more easily calculate the cost of investing in Iraq. A stable interest rate is also correlated with a stable inflation rate, which is very important.
Because the Iraqi government was to peg the currency to the U.S. dollar, it has to establish capital controls (otherwise, the foreign-currency regime would be free-floating).
