  1. Early and substantial action to keep well clear ✔
  2. Small course changes made at the last moment
  3. No action until the other boat signals

Why: Rule 16 says a give-way vessel must, so far as possible, take early and substantial action to keep well clear. A big, obvious turn or slowdown made in good time tells the other boat exactly what you're doing.
