Post a picture next time with your question so we can better help you (:
I feel like it is D. The war between good and evil
The answer would be : Radio Media led to the end of Print Media
Radio did not end the print media. The development of digital media such as Website's encyclopedia, Ebook and PDF Formats, handheld tablets that could contain over 100,000 books in one tablet, etc
I believe D would be the most reasonable answer for this question given that it has factual information that well suits a topic sentence.
