The correct answer is D. All of these.
A research problem is feasible only when it is researchable, new and adds something to knowledge, and has utility and relevance.
A research problem is researchable if it can be studied using the available methods and resources. A research problem is new and adds something to knowledge if it is not already well-known or if it provides a new perspective on a known problem. A research problem has utility and relevance if it is important and has the potential to make a difference in the world.
Here is a more detailed explanation of each of these criteria:
- Researchable: A research problem is researchable if it can be studied using the available methods and resources. This means that the problem must be well-defined and that there must be a way to collect data about it. For example, if you want to study the effects of a new drug, you need to be able to identify the people who will take the drug and measure their health before and after they take it.
- New and adds something to knowledge: A research problem is new and adds something to knowledge if it is not already well-known or if it provides a new perspective on a known problem. This means that you need to be able to show that your research will make a contribution to the existing body of knowledge. For example, if you want to study the effects of a new drug, you need to be able to show that your research will provide new information about the drug’s safety and efficacy.
- Has utility and relevance: A research problem has utility and relevance if it is important and has the potential to make a difference in the world. This means that your research needs to be focused on a problem that is important to people and that your findings have the potential to make a positive impact. For example, if you want to study the effects of a new drug, you need to be able to show that your research will have the potential to improve the lives of people who take the drug.
In conclusion, a research problem is feasible only when it is researchable, new and adds something to knowledge, and has utility and relevance.
