Thank you for the opportunity to help you with your question!
The road map of an essay is similar to an outline, or a list of mini-thesis statements. Each one leads to the next, thus the name "road map". It can also be seen as splitting apart a thesis statement. Here is an example:
Music has been gradually deteriorating in both creative and audio quality, and music labels will make up for their decreasing quality by effectively "brainwashing" their listeners through effects similar to Stockholm syndrome.
1. Music has been deteriorating in creative quality.
2. Music has been deteriorating in audio quality.
3. Music labels brainwash their listeners
4. Compare effects of Stockholm syndrome to music industry.
I can't see what the fourth option is on the question, so I'm going to assume it's something along the lines of "all of the above". But that doesn't matter because a road map will definitely not have cited evidence from sources. Therefore, the answer is A, cited evidence from sources.
Please let me know if you need any clarification. I'm always happy to answer your questions.
