A person whose opinions change rapidly is described as

• A. Volatile
• B. Waver
• C. Whimsical
• D. Zeal

Answer: (A)

Volatile captures the idea of opinions that change quickly and unpredictably. It’s used to describe things—moods, conditions, or attitudes—that don’t stay the same for long, signaling instability in a person’s stance. The other options don’t fit as well: to waver is more about hesitating or alternating between options in the moment, not describing a lasting trait; whimsical suggests playful or fanciful unpredictability rather than rapid shifts in opinions; zeal denotes strong enthusiasm, not changing beliefs. So the best fit is volatile.
