Let's start first by using process of elimination. Usually, when given multiple choice, we can eliminate two answers right away. In this case, I would eliminate A and D, because those answers make no sense and appear far-fetched.
Now let's move on to B and C. Obviously both of these answers have bearing, however, our job is to chose the <em>best </em>answer. According to Google, the Star Trek effect is the cultural influence Star Trek has on the nation, for example, promoting interracial kissing and a diverse cast. Therefore, my best guess would be C, because it is a cultural aspect.
If my answer was correct, please let me know, and give me brainliest answer!
