Which word describes a willingness to do or accept something?

• A. Keen
• B. Averse
• C. Disinterested
• D. Obstacle

Answer: (A)

The word that describes a willingness to do or accept something is "keen." When someone is keen, it indicates enthusiasm and eagerness towards an activity or proposal, showing an open and positive attitude. This term suggests an individual's readiness to engage and participate, which embodies the essence of willingness.

In contrast, other options do not convey this positive acceptance. "Averse" refers to a strong dislike or reluctance towards something, making it an unsuitable choice. "Disinterested" implies a lack of interest or concern, suggesting indifference rather than willingness. Lastly, "obstacle" signifies something that prevents movement or progress and does not relate to a person's willingness at all. Thus, "keen" stands out as the clear descriptor of a positive, willing attitude.
