Countries with greater potential for economic growth and lower tax rates on corporate earnings may attract DFI (direct foreign investment), which can increase their current account balance. A relatively high home inflation rate tends to increase imports and decrease exports, leading to an increase in the current account balance. However, a high growth in the home income level relative to other countries would lead to an increase in imports due to increased purchasing power, which can contribute to a decrease in the home country's current account balance.
Therefore, the correct answer is A. III only.
