How can B be elimnated

Hi @avif, Thanks for the question! Well, so the stimulus is saying you shouldn’t restrict the performance of activities unless there are negative effects on others. Now, let’s take a look at (B). In (B), we have a scientist who invents a technology, and we’re saying that other people should be able to profit from it too. Since there’s no evidence that letting others will negatively effect the scientist. So this is saying we shouldn’t restrict others from profiting, since there are no negative effects on the scientist. But this is what the principle says: don’t restrict things if they don’t have negative effects. No negative effects here, so no restriction. (B) is in line with the principle, and so can’t be the correct answer. Hope this helps! Feel free to ask any other questions that you might have.

Thanks

Glad I helped!
