The question is about understanding the term for the language conversion process. 'Translation' is the correct term for converting text from one language to another while preserving the meaning and nuances. 'Transcription' refers to converting spoken words into written form. 'Transmutation' means changing one thing into another, often used in a scientific or alchemical context. 'Interpretation' can involve explaining the meaning of something, but it is not the primary term for the language conversion process. Therefore, the correct answer is B. Translation.
