Answer:

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).
