English Grammar After x rays were discovered in 1895, there were some preposterous reactions. For examples, London merchants sold X-ray proof underwear.

व्याख्या:- Preposterous means contrary to reason or common sense; utterly absurd or ridiculous. Origin; mid 16th century: from Latin praeposterus ‘reversed, absurd’ (from prae ‘before’ + posterus ‘coming after’) + -ous. So, C is correct answer.
