Answer: Choice D 
Reason:
Exponential functions have the variable in the exponent.

Choice C is a rational function because it is a ratio of two polynomials. This rules out choice C.
Choice D is the only function with the variable in the exponent. That is assuming you meant to say instead of 
To find the l.a., you multiply the perimeter of the base (the hexagon) by the height.
l.a. = 60 x 12
surface area is harder :(
you have to find the apothem and all that jazz. sorry i can't help more, good luck!
