Choose the correct answer from the options given below:

1. (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
2. (A) - (IV), (B) - (III), (C) - (II), (D) - (I)
3. (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
4. (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Option 1 -> (A) affected fits (II) as past tense verb; (B) affectation fits (IV) as noun for pretentious behavior; (C) affection fits (I) as noun for love; (D) effective fits (III) as adjective for successful methods.

Option 2 -> Incorrect matching: "affected" doesn't fit sentence (IV) about irritating behavior, and "effective" doesn't fit sentence (I) about mother's feelings.

Option 3 -> Incorrect matching: "affectation" doesn't fit sentence (I) about mother's feelings, and "affection" doesn't fit sentence (IV) about irritating behavior.

Option 4 -> Incorrect matching: "affected" doesn't work in sentence (III) which needs an adjective, and "effective" doesn't work in sentence (II) which needs a past tense verb.

Hence, Option 1: (A) - (II), (B) - (IV), (C) - (I), (D) - (III) -> "Affected" (verb) correctly completes "flood has greatly affected the region"; "affectation" (pretentious behavior) fits "irritating affectation"; "affection" (love/care) fits "mother's affection"; and "effective" (adjective) fits "proved very effective" -> correct
