Option 1 -> (A)-(I) incorrect: "flicker of emotion" doesn't describe children's activity; (C)-(IV) incorrect: "flurry of activity" doesn't fit cold eyes.
Option 2 -> (A)-(II) incorrect: "touch of sadness" doesn't match children fetching colors; (C)-(IV) incorrect: "flurry of activity" cannot be detected in eyes.
Option 3 -> (A)-(IV): "flurry of activity" perfectly describes busy children fetching colors; (B)-(III): "glimmer of hope" suits improving company figures; (C)-(I): "flicker of emotion" is what you'd detect in eyes; (D)-(II): "touch of sadness" fits voice conveying tragic news.
Option 4 -> (A)-(III) incorrect: "glimmer of hope" doesn't describe children's actions; (B)-(IV) incorrect: "flurry of activity" doesn't describe company figures.
Hence, Option 3: (A) - (IV), (B) - (III), (C) - (I), (D) - (II) -> Each phrase matches the context perfectly: children create activity, company figures offer hope, eyes show emotion, and voice carries sadness for tragic news -> correct
