Which word describes someone who is aggressively defiant?

• A. Abstruse
• B. Infinitesimal
• C. Truculent
• D. Adjunct

Answer: (C)

Truculent describes someone who is aggressively defiant—hostile, combative, and quick to challenge others. This mood conveys a belligerent stance, opposite of calm or cooperative discussion, which is exactly what “aggressively defiant” signals. The other words point to unrelated ideas: abstruse means hard to understand, infinitesimal means extremely small, and adjunct is something added or supporting. For example, a truculent response in a discussion might snap at others and refuse to yield, illustrating the aggressive defiance.
