I've fallen and I can't get up

A) Avalanche can't stop 91-year-old hiker
B) Dog thrown off overpass by stranger
C) Fireworks fall into Wrestlemania crowd

A) is fake.
A Utah dog (B) was thrown off an overpass (she's recovering well), and fireworks and cables (C rained onto the audience of an Orlando Wrestlemania show (they're recovering well).
See which headline is fake.
