Select the most appropriate ANTONYM of the given word. Miserable

The word 'Miserable' describes a state of great unhappiness, discomfort, or distress. To find the antonym, we must identify a word that expresses the opposite sentiment of happiness or well-being. 'Cheerful' means noticeably happy and optimistic, which directly contrasts with the sadness implied by 'Miserable'. Therefore, Option D is the correct choice. \\[n]Other options are incorrect because 'Melodious' refers to pleasant sound, not emotional state. 'Settled' implies stability or resolution of a dispute, and 'Restrained' suggests holding back emotions; neither serves as a direct opposite to misery. Thus, the most appropriate antonym for 'Miserable' is 'Cheerful'.
