A. Reliable
B. Flawless
C. Imperfect
D. Honest
🧠 Explanation:
The antonym of “infallible,” meaning perfect or error-free, is “imperfect,” indicating flaws or susceptibility to mistakes. Used in contexts like technology or human judgment, “imperfect” contrasts with the idea of faultlessness, as in “an imperfect system.” Understanding antonyms enhances language precision, vital for clear communication in writing, debates, or technical discussions. This knowledge aids English learners and professionals in articulating distinctions effectively, ensuring clarity in describing reliability or accuracy in various scenarios, from academic essays to professional evaluations.
