A research problem is not feasible only when :

It is researchable
It is new and adds something to knowledge
It consists of independent and dependent variables
It has utility and relevance

The correct answer is: A. It is researchable.

A research problem is not feasible only when it is not researchable. This means that the problem is not something that can be studied or investigated using scientific methods. For example, a research problem that asks “What is the meaning of life?” is not researchable because it is not possible to test or measure the meaning of life.

The other options are not correct because they are all characteristics of a feasible research problem. A research problem is feasible if it is:

  • Researchable: The problem can be studied or investigated using scientific methods.
  • New and adds something to knowledge: The problem is not already well-studied and the research will add new knowledge to the field.
  • Consists of independent and dependent variables: The problem can be broken down into variables that can be manipulated and measured.
  • Has utility and relevance: The problem is important and has the potential to make a difference in the world.
