Option 1 -> (A) - II is incorrect; ashen-faced means pale/colorless, not marked with fungus.
Option 2 -> (A) ashen-faced = III (pale or colourless); (B) gingerly = IV (in a careful way); (C) Doric facade = I (old architectural front); (D) blacked with mildew = II (marked with fungus) - all matches are accurate.
Option 3 -> (A) - IV is incorrect; ashen-faced doesn't mean careful, and gingerly doesn't mean pale.
Option 4 -> Multiple mismatches; ashen-faced is not an architectural term, and the other pairings are also wrong.
Hence, Option 2 -> "Ashen-faced" describes the elderly woman's pale complexion; "gingerly" shows Murugan's cautious movement on splintered planks; "Doric facade" refers to the classical architectural front of the building; and "blacked with mildew" describes the fungus-stained plaster -> correct
