Course of Action I: While allocating more funds for rice research seems beneficial, it may not be the immediate solution needed to address the food supply challenge as stated.
Course of Action II: Encouraging people in Asia to change their food habits can help diversify food sources and alleviate the pressure on rice supplies. This is a strong and proactive course of action.
Course of Action III: Growing rice in countries outside Asia can help meet the demand and ensure that supply chains are diversified. This is also a valid course of action, as it addresses potential challenges in rice production within Asia.
So, the correct option is (D): Only II and III follow.
