  2. 1,200 feet AGL
  3. 700 feet AGL ✔

Why: Class E transition areas begin at either 700 feet AGL or 1,200 feet AGL. The faded magenta edge on a sectional chart marks 700 feet, and the faded blue edge marks 1,200 feet.

Huh, didn't know that: The 700-foot and 1,200-foot Class E transition areas stay in effect continuously, regardless of airport operating hours.
