The ETS has also conveniently shaded the correct answer for you.

That is not entirely true. In region A is is definitely a liquid. In region C it is definitely vapor.
Follow the path from one isotherm through the region (lets go left to right with 4). Due to high pressure, it's condensed into a liquid. As pressure decreases, and temperature increases, it starts to evaporate into a liquid. Pressure stays the same for a phase transition, so the volume increase as more and more liquid transitions into a gas. Eventually, when the isotherm exits the shaded region, it is a gas.
Now following the critical isotherm, 2, we see it skips this whole process.
The region E is most likely a liquid, the region A is a liquid, the region C is a gas, and the region B is transition region where Vapor and Liquid are in equilibrium. Thus, the answer is B.
You might ask "What about D?" Well, the distinction between gas and liquid falls apart up here. You'll get something that can only be classified as both. This is called a supercritical fluid and an excellent video you should watch is here: http://www.youtube.com/watch?v=yBRdBrnIlTQ
