Step-by-step explanation:
The term "wise guy" typically refers to someone who is overconfident in their knowledge or intelligence, often in an irritating way. Among the options provided, both 'wiseacre' and 'smart alec' are synonymous with 'wise guy.' However, if we must choose the closest match, option b) smart alec would be the most accurate as it specifically connotes a person who is irritatingly smug and clever in an impertinent or flippant manner.
'Wiseacre' also holds a similar meaning but can sometimes be less about smugness and more about pretension. 'Witling' and 'know-all' describe someone who fancies themselves witty or very knowledgeable, but these terms don't carry the same connotation of irritation that 'smart alec' does in relation to 'wise guy.' Therefore, the most correct answer is b) smart alec.
