Option 1 -> Incorrectly matches Bellicose with "peculiar habit" and Dyslexia with "no longer in practice"
Option 2 -> Incorrectly matches Bellicose with "no longer in practice" and Dyslexia with "one who is fond of fighting"
Option 3 -> Incorrectly matches Bellicose with "a learning disorder" and Dyslexia with "one who is fond of fighting"
Option 4 -> Correctly matches all words: Bellicose (warlike/aggressive) with "one who is fond of fighting", Dyslexia with "a learning disorder", Idiosyncrasy with "peculiar habit of a person", and Obsolete with "no longer in practice"
Hence, Option 4: (A) - (II), (B) - (IV), (C) - (I), (D) - (III) -> This is the accurate matching as Bellicose means aggressive/warlike, Dyslexia is indeed a learning disorder affecting reading, Idiosyncrasy refers to a person's distinctive characteristics or habits, and Obsolete means outdated or no longer in use -> correct
