3. Put the line all by itself in a paragraph to make it stand out more.
I especially like this one. The very start should be at most a short-ish paragraph, a hook that's easy to take in one bite.
One variation of this is to put it in intense dialog-- if it's soon followed by description, not just the start of some loud talking heads. (My current WIP starts with simply "Dammit, Angie--" and then the description of how the hero's running for his life.)
