Thanks for the question! So remember, we want something that basically is an application of the principle the philosopher says. And the philosopher basically says “it’s ok to find truths that we don’t like.” so take a look at (B), which applies that in the research context. We shouldn’t hide from truths (the research), even if it leads to bad things (like making sophisticated weapons).
Hope this helps! Feel free to ask any other questions that you might have.
