Option 1 -> Creates incorrect collocations: "representative on a new venture" and "subject of the group" are grammatically wrong.
Option 2 -> All pairings are incorrect: "representative with each other" and "subject on a new venture" don't follow standard English usage.
Option 3 -> Only one correct pairing (D-III); fails with "representative on" and "subject of" which are improper collocations.
Option 4 -> All collocations are grammatically correct: "representative of" (the group), "subject to" (change), "embark on" (a venture), and "compatible with" (each other).
Hence, Option 4: (A) - (II), (B) - (IV), (C) - (I), (D) - (III) -> These prepositional phrases follow standard English collocations where specific prepositions pair with certain words to convey proper meaning -> correct
