Concept:The underlined word "abrupt" describes something that happens suddenly or without warning.
The task is to select the option closest in meaning to this idea.
Explanation:The word "abrupt" usually refers to an action or event that occurs unexpectedly and with little or no notice.
Let us compare each option to determine the best match.
"Sharp" mainly suggests intensity or keenness, such as a sharp pain or a sharp turn, and does not necessarily mean unexpected.
"Brisk" means energetic, lively, or quick in a steady and active way, like a brisk walk, but it lacks the sense of surprise.
"Quick" simply indicates speed or rapidity and does not imply that an event happens without warning.
"Sudden" describes something that occurs without warning or all at once, which is precisely what "abrupt" means.
Hence, "sudden" is nearest in meaning to "abrupt."
Answer:D. sudden
