Why not all three? Triple redundancy.

One idea is to use a "gravity tug", a ship or satellite that flies up next to the asteroid and uses its gravity to gradually alter the asteroid's course. Obviously that's intended to be part of a long-term plan, as the effect would be very gradual.
Blowing up tons of nukes on one side of it should have some effect.
