Select the option that can be used as a one-word substitute for the highlighted group of words.
His speech was full of words that sound impressive but have little meaning.

Correct option is B

The correct option is (b).

The phrase “words that sound impressive but have little meaning” refers to language that is pompous, inflated, and showy, used mainly to impress people rather than to convey clear ideas. The one-word substitute for such exaggerated and high-sounding speech is bombast (Hindi meaning: आडंबरपूर्ण / खोखला दिखावटी भाषण).

Bombast is used when someone employs grand words and dramatic expressions, but the content is shallow and lacks real substance.

Example: The politician’s address was pure bombast, filled with grand promises but no practical plan.

Meanings of the other given options:

• (A) prose: Ordinary written or spoken language, not poetry (Hindi: गद्य).
• (C) rhetoric: The art of effective or persuasive speaking/writing; sometimes also refers to impressive language (Hindi: वाक्-कला / प्रभावशाली भाषण शैली), but it does not necessarily mean meaningless show.
• (D) jargon: Special words/terms used by a particular profession or group (Hindi: तकनीकी शब्दावली).
