A: Video games have negative effects on teenagers.
Explanation:
The question what the author's overall opinion on video games is. So, the reader should find the main idea of the passage. Throughout the text, the author brings up many problems video games cause like lack of activity, lack of friends, and worse grades. The author also brings up more effects video games have. Since the majority of the text is about overall negative effects on teenagers it is clear that A is correct. Additionally, much of the author's dictation has negative connotations. So, it is safe to say that they do not support video games. This is another indicator of the author's viewpoint.
