The two correct reasons to change your research question are:
-
When it does not match the scope of your project - If your research question is too broad or too narrow and does not align with the overall aim of your project, it may need to be adjusted.
-
When new information leads you to a different topic - As you conduct research and discover new information, it may prompt you to refine or change your research question to better fit the emerging insights.
The other options are less valid as reasons for changing the research question. It's important for the research question to be interesting and for there to be enough sources to support it, but these do not necessarily warrant a change.
