Select the option that can be used as a one-word substitute for the given phrase.
Waver between different opinions or actions.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Vacillate.
"Vacillate" precisely captures the idea of indecision or hesitation, suggesting a back-and-forth movement between different opinions or actions.
It conveys the notion of being unable to settle on a particular course of action or viewpoint.
The other options - "sway," "viaduct," and "thrifty" - do not accurately represent the concept of wavering between different opinions or actions.
Therefore, "vacillate" is the correct choice for the one-word substitute.
