To waver between different opinions or actions; to be indecisive.

To waver between different opinions or actions; to be indecisive.

• A. Oscillate
• B. Vacillate
• C. Waver
• D. Hesitate

Answer: (B)

The idea being tested is choosing a word that shows mental back-and-forth between options. Vacillate fits best because it specifically means to swing back and forth between different opinions or courses of action, signaling ongoing indecision. Oscillate also involves back-and-forth motion, but it’s often used for physical movement or fluctuating trends rather than a decision-making process. Waver and hesitate are close, but waver can be more general about uncertainty, and hesitate centers on pausing before acting rather than continually weighing between alternatives. In context, someone who vacillates between a strict or lenient stance is repeatedly weighing choices, highlighting the indecisive, deliberative back-and-forth that vacillate conveys.
