Choose the synonym of DILIGENT.

**The reasoning** A synonym is a word with the **same or similar meaning**. DILIGENT means showing care, effort, and persistence in your work — essentially working hard and thoroughly. Think of a diligent student: they attend classes regularly, complete assignments on time, and put in serious effort. That's exactly what "hardworking" describes. **Hardworking** = putting in consistent effort and dedication = **DILIGENT** **Why the wrong options tempt you** - **Lazy** is actually an *antonym* (opposite) — the exam setters know some students rush and confuse synonyms with antonyms - **Careless** is another opposite — diligent people pay attention to detail, careless people don't - **Slow** might confuse you because diligent people are thorough, but "slow" refers to speed, not effort quality. You can be diligent and fast! **Quick takeaway** DILIGENT = HARDWORKING — both describe someone who puts in serious, consistent effort; always match the *positive quality* of dedication, not speed or laziness.
