A recommended policy for developing countries to stimulate economic growth would be

A) abolishing central banks.
B) more central planning by government.
C) encouraging more direct foreign investment.
D) expanding employment in state industries.

Encouraging more direct foreign investment can bring in much-needed capital, technology, and expertise to developing countries, boosting economic growth. Additionally, it can create jobs and provide access to new markets for domestically produced goods and services. Abolishing central banks or expanding employment in state industries can lead to inefficiencies and bureaucratic burdens, while more central planning by government can stifle innovation and entrepreneurship.
