In this section an underlined word has been used variously in three sentences S1, S2 and S3. You are required to determine in how many sentences has the word been used correctly. S1: He displayed real chutzpah while facing the belligerent opposition all by himself. S2: The lawyer displayed rare chutzpah in presenting tectonic evidence in court that changed the track of the case entirely. S3: He ran with chutzpah to secure first prize at the award ceremony.

Chutzpah is a Yiddish-origin word meaning audacity, nerve, or shameless boldness — usually with a connotation of impudent courage. In S1, facing belligerent opposition single-handedly with chutzpah correctly captures bold audacity. In S2, the lawyer showing bold nerve in presenting case-changing evidence is also a correct usage. In S3, 'ran with chutzpah' is incorrect because chutzpah refers to attitude/nerve, not physical speed or effort in a race. Therefore the word is used correctly in 2 sentences, making the answer (b) 2.
