💡 Detailed Explanation
The prefix '非' (hi-) is used to mean 'non-', 'un-', or 'anti-'. '非科学的' (hikagakuteki) means 'unscientific'. '不' (fu-) is used for concepts like impossibility or inconvenience (e.g., 不可能). '未' (mi-) means 'not yet' (e.g., 未完成). '無' (mu-) means 'without' or 'lack of' (e.g., 無関係). In this context, 'unscientific' is the most appropriate meaning.
