What does 'alacrity' signify?

Alacrity specifically denotes a cheerful readiness or eagerness to do something, often accompanied by promptness. The term suggests a lively and eager willingness to engage in tasks or activities, indicating not just the ability to act but doing so with enthusiasm and speed. This quality is often appreciated in various contexts, such as in response to requests, teamwork scenarios, or any situation where enthusiasm is beneficial for actions to be carried out efficiently and effectively.

In contrast, the other options present concepts that are entirely opposite or unrelated to this notion of eagerness and liveliness. Indifference reflects a lack of interest or concern, procrastination indicates a delay in action, and reluctance suggests hesitation or unwillingness, all of which are contrary to the spirit of alacrity.
