You've been unclear this whole time about which battle format you're aiming for, so I'm assuming you want doubles based on your previous post.
Explosion can work on some Pokémon, but Ferrothorn is just too slow and not strong enough to make good use of it. You're better off just letting the opponent KO you and possibly take Iron Barbs (and perhaps Rocky Helmet) damage, or even waste the opponent's moves with Protect while your other Pokémon takes advantage.
Rest makes you asleep far too long to be useful, especially with the fast-paced nature of double battles. If you want some recovery, Leech Seed and/or Leftovers are much more useful.
Bulldoze has minor uses in lowering opponents' Speed, but comes with the major drawback of you needing to have a partner immune to Ground or using Protect in order to make it work, or else your other Pokémon will also suffer the lowered Speed and negate any benefits of the move (don't expect it to do any sizable damage and definitely don't expect Ferrothorn to outspeed anything even with Bulldoze). There are also many common Pokémon in doubles that are airborne, further reducing its utility.
You may think Rayquaza was just thrown in, but the mere fact that it is allowed in the battle format you are intending to participate in changes everything. If you're allowed to use Rayquaza, your opponent is therefore also allowed to use Rayquaza and any other similar legendaries, which will likely make short work of your team if you don't also use such Pokémon.
