The question you're referring to is likely from (the original flash game by Splapp-me-do).

Some players might overthink it (expecting a trick, like clicking the word "42" on the question text rather than the option button), but the intended solution is simply choosing B) 42 . Final verdict: This is one of the few fair, non-trolling questions in the game. If you know the reference, you pass easily. If not, you might waste a life guessing. Difficulty: Easy (once you know the reference) Trickiness: Low Satisfaction: Mild — it’s a relief after frustrating earlier questions.

In this case, however, 42 the correct answer, and clicking it advances you to the next question. There is no hidden twist here (unlike other questions where clicking the obvious answer kills you).
