Answer:
The correct answer is:
a)
By reducing the level of real interest rates at home,
foreign and domestic investors will invest in some
other nation, where they can get a higher real rate
of return. However, this process would involve the
selling of the home currency, which will result in
its devaluation. Similarly, by increasing income
levels in the domestic economy, imports will naturally
increase. This process too, will involve the selling
of the home currency in order to buy the currency
of the nation from where the imports are being bought.
