Which word means serious; grave?

• A. Solemn
• B. Fervor
• C. Coquette
• D. Dispassionate

Answer: (A)

You’re looking for a word that means serious or grave. Solemn directly conveys that weighty, dignified sense—describing moods, occasions, or attitudes that are meant to be taken seriously and with formality. For example, a solemn ceremony or a solemn vow shows gravity and seriousness.

Fervor, by contrast, refers to intense passion or enthusiasm, which isn’t about seriousness. Coquette means a flirt, a person who charms for romantic effect, not seriousness. Dispassionate describes being emotionally neutral or calm, which can imply impartiality but not the grave, weighty seriousness the prompt asks for.

So, the best choice is solemn because it most precisely captures the idea of seriousness and gravity.
