Therefore, both option B "miserable" and option C "sad" are antonyms for the word "cheerful". However, since the question seems to imply that there is only one correct answer , and "miserable" is more intense than "sad", the best choice would be option B "miserable'". (Answer): B

**B) Miserable **

**Kata "miserable" adalah antonim dari kata "cheerful". Meskipun "sad" juga merupakan antonim, "miserable" lebih tepat karena lebih intens dalam konteks ini.
