A research problem is feasible only when it is

It is researchable
It is new and adds something to knowledge
It has utility and relevance
All of these

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.
