Option 1 -> Incorrect matching: "ramped up" doesn't fit sentence A which needs support/help context.
Option 2 -> Correct matching: (A) rallied around = came together to support; (B) ramped up = increased; (C) railed against = criticized strongly; (D) raked up = brought up past issues.
Option 3 -> Incorrect: Places "rallied around" in sentence C which needs criticism, not support.
Option 4 -> Incorrect: Places "raked up" in sentence A which needs support context, not bringing up old issues.
Hence, Option 2: (A) - (IV), (B) - (I), (C) - (II), (D) - (III) -> "Rallied around" means people united to help someone in need; "ramped up" means to increase/intensify (security); "railed against" means to criticize vehemently; "raked up" means to bring up unpleasant past matters. Each phrasal verb perfectly matches the context of its sentence. -> correct
