Which is an effective research question in developing an essay topic? a. who are some important greek heroes? b. who are hercules’s mother and father? c. what is the most interesting story based on a greek myth? d. what is the story of hercules, and what lesson does it teach?

D. What is the story of Hercules, and what lesson does it teach?

Explanation:

The chosen research question for an essay topic is effective because it is answerable , complex , specific  and attractive. Therefore, the essay will probably include interesting facts of Hercules' life and a moral.

The rest of the options are incorrect because the questions are either too broad or vague, or express a view or judgment about something, which is not necessarily based on fact.
