Complete the sentences given in List-I with the appropriate adverbs given in List-II:

List-I	List-II
(Sentences)	(Adverbs)
(A) Since he got that haircut, I can _____ recognize him.	(I) slowly
(B) On the day of the performance, Sam played the piano more _____ than Thomas.	(II) heavily
(C) How will we reach home on time? The bus is going rather ____.	(III) barely
(D) It was raining so ____ that many drains started overflowing.	(IV) skillfully

Choose the correct answer from the options given below:

Option 1 -> (A)-(I), (B)-(II), (C)-(III), (D)-(IV): Incorrect pairing - "slowly" doesn't fit with recognition difficulty, and "heavily" doesn't describe piano playing.

Option 2 -> (A)-(I), (B)-(III), (C)-(II), (D)-(IV): Incorrect pairing - "slowly" and "barely" are misplaced, and "skillfully" doesn't fit rain description.

Option 3 -> (A)-(II), (B)-(I), (C)-(IV), (D)-(III): Incorrect pairing - "heavily" doesn't describe recognition, and all other adverbs are mismatched.

Option 4 -> (A)-(III), (B)-(IV), (C)-(I), (D)-(II): Correct matching - "barely" (almost not) for difficult recognition, "skillfully" for piano performance comparison, "slowly" for bus speed causing delay, "heavily" for intense rain causing overflow.

Hence, Option 4 -> The sentence contexts require: (A) an adverb showing difficulty recognizing someone after a dramatic haircut change = "barely"; (B) an adverb comparing performance quality = "skillfully"; (C) an adverb explaining why they'll be late = "slowly"; (D) an adverb describing rain intensity that causes flooding = "heavily" -> correct
