a) 3.6*10^(-3) m^2

Explanation:

a) is the only possibly correct answer since the other two have units which are not areas (both m and mm are linear measures).

We can verify the area using the Surface Area formula
color(white)("XXX")A = 4pir^3

The only possible trick here is in converting between cm^3 and m^3 (or maybe handling scientific notation).
