You don't have enough information to make sense. STP doesn't depend upon the gas; it is 1 atm pressure and 273 K for temperature for ANY gas.
The question just says:
Which of the following has the highest conentration in air at STP?
a)He
b)H2O
c)CO2
d)N2
e)O2
the answer was N2
Which of the following has the highest conentration in air at STP?

but I don't know how to get that answer
You look it up in a table. N2 is about 79%, O2 about 20%, He, H2O, and CO2 lesser amounts making up the rest. Here is a site that will give you the information.
