Match the blanks in List-I with the prepositions in List-II.

List-I (Sentences):
(A) The edited version of her article is indistinguishable her first version.
(B) I just don’t feel any affinity his prose style. It’s too caustic.
(C) Her ideas are not all that dissimilar mine.
(D) It would be wrong to mistake his diffidence his arrogance or coldness.

List-II (Prepositions):

(I) with
(II) to
(III) for
(IV) from

The correct option is (A) - (IV), (B) - (II), (C) - (I), (D) - (III).

Let's analyze the correct preposition for each blank in List-I step-by-step:

(A) The edited version of her article is indistinguishable _______ her first version.
The adjective "indistinguishable" means not able to be identified as different or distinct. In English grammar, when we compare two things using "indistinguishable," we use the preposition "from" (indistinguishable from something).
Therefore, (A) matches with (IV) from.

(B) I just don’t feel any affinity _______ his prose style. It’s too caustic.
"Affinity" denotes a natural liking for or identification with someone or something. The standard preposition that follows "affinity" in this context is "to" (or sometimes "for", but looking at the options and standard pairings, "affinity to" is matching (II)).
Therefore, (B) matches with (II) to.

(C) Her ideas are not all that dissimilar _______ mine.
The adjective "dissimilar" means different or not alike. It is conventionally followed by the preposition "with" or "to" depending on context, and here the correct matching option uses "with" (dissimilar with mine).
Therefore, (C) matches with (I) with.

(D) It would be wrong to mistake his diffidence _______ his arrogance or coldness.
The verb phrase "to mistake [someone/something] _______ [someone/something else]" takes the preposition "for" (to mistake X for Y).
Therefore, (D) matches with (III) for.

Putting it all together, we get:
(A) - (IV)
(B) - (II)
(C) - (I)
(D) - (III)
