Synonym of HAPPY.

**The reasoning** A synonym is a word that has the **same or nearly the same meaning** as another word. "Happy" means feeling joy, pleasure, or contentment. Looking at our options, "Glad" also means experiencing joy or pleasure — it's essentially another way to say you're happy. They're interchangeable in sentences like "I'm happy to see you" or "I'm glad to see you." **Why the wrong options tempt you** Options A, C, and D all rhyme with "Glad" (Sad, Mad, Bad), which is the trap! Exam setters know students rushing through might pick based on sound patterns rather than meaning. "Sad" is actually an **antonym** (opposite) of happy. "Mad" means angry or crazy. "Bad" means not good. They sound similar but mean completely different things. **Quick takeaway** Don't let rhyming words fool you — synonyms are about **meaning**, not sound; "happy" and "glad" both describe feeling good, so they're perfect synonym partners.
