1. Fixed Alternative: The research problem has a finite and fixed set of answers. The researcher is required to choose one or more correct answers from the given set of options. This choice of answer problem can further be classified into objective-type and subjective-type questions.
- Objective-type questions have a clear and definitive answer. The researcher is not required to provide any justification or explanation for their answer.
-Subjective-type questions require the researcher to provide their opinion, judgment, or interpretation. There may be multiple correct answers, and the researcher's answer may be influenced by their subjective experiences, beliefs, or values.
2. Open-Ended: The research problem does not have a pre-defined or fixed set of answers. The researcher is free to respond to the research question in their own words and provide their own interpretation, analysis, or synthesis. Open-ended questions encourage creativity, exploration, and in-depth understanding.
