Which word means useless or without practical effect?

• A. Futile
• B. Behoove
• C. Chastise
• D. Sinuous

Answer: (A)

The main idea here is identifying a word that describes something as useless or producing no practical result. That sense is captured by futile. When something is futile, the effort won’t lead to a useful or desired outcome, even if you try hard. For example, repairing a broken watch with no parts available would be futile because there’s no way to restore its function.

Behoove means it would be wise or proper for someone to do something; it’s about advisability or obligation, not usefulness. Chastise means to scold or punish someone for misbehavior. Sinuous describes a winding, curving, or flexible form or movement. None of these convey the idea of being useless or without practical effect the way futile does.
