Which word is the best antonym for 'facilitate'?

• A. Hinder
• B. Assist
• C. Enable
• D. Promote

Answer: (A)

Facilitate means to make a process easier or help something proceed. An antonym is something that blocks or slows progress. Hinder fits best because it means to create obstacles or delay, which is the direct opposite of making things easier or moving forward. The other options all imply helping or enabling progress—assist means to help, enable means to provide the means to do something, and promote means to encourage or advance. None of those oppose progress, so they aren’t antonyms. For example, facilitating a project flow helps it move smoothly, whereas hindering would slow it down or stop it.
