(A) "get over" (IV) -> means to recover from or cope with a difficult emotional situation like the death of a loved one.
(B) "get up" (III) -> means to wake up or rise from bed in the morning.
(C) "get off" (I) -> means to exit or disembark from a vehicle like a bus.
(D) "get on" (II) -> means to board or catch a vehicle like a train.
Hence, Option 4: (A) - (IV), (B) - (III), (C) - (I), (D) - (II) -> Each phrasal verb correctly fits the context: "get over" for emotional recovery, "get up" for waking early, "get off" for leaving the bus, and "get on" for boarding the train -> correct
