The statement "A country that has a fixed-exchange-rate regime: can still conduct independent monetary policy" is correct.

Here's why:

1. A fixed exchange rate regime is a method used to stabilize the value of a currency by directly fixing its exchange rate value to a predetermined value for another currency or gold.

2. The central bank can still conduct independent monetary policy under a fixed exchange rate regime. However, it's important to note that the policy's effectiveness may be limited. This is because the central bank must intervene in the foreign exchange market to maintain the fixed rate, which can involve increasing or decreasing the money supply.

3. If the central bank wants to tighten monetary policy (i.e., reduce the money supply to combat inflation), it may conflict with the need to maintain the fixed exchange rate. For example, if the domestic currency is under pressure to depreciate, the central bank would need to buy its own currency (thereby reducing the money supply). But if it also wants to reduce the money supply to combat inflation, these two goals can conflict.

4. Therefore, while a country with a fixed exchange rate can technically conduct independent monetary policy, its ability to do so effectively can be constrained by the need to maintain the fixed exchange rate.

5. The other statements are generally incorrect. A country with a fixed exchange rate is not necessarily more likely to inflate the money supply than a country with a floating exchange rate. It also still has the ability to implement capital controls. And while its monetary policy may be constrained, this does not mean it "can never have a central bank that can conduct independent monetary policy."
