Answer: Choice A

================================================

Step-by-step explanation:

The portion that has 2pi*r^2 represents the two base areas (think of the top and bottom of a can). The 2*r*pi*h is the lateral surface area, which can be thought of as the area in which the label covers. So put together the total surface area of the entire cylinder is 2pi*r^2 + 2*r*pi*h

note: 2*r*pi*h is the same as 2pi*r*h
