d.) 4Na + 0(2) --> 2Na(2)O
4 Na --> 4 Na
2 O --> 2 O
balanced
B) 2Na(2) + O(2) --> 2Na(2)O
4 Na --> 4 Na
2 O ---> 2 O
balanced
a) is not balanced 1 vs. 2 Na and 2 vs. 1 O
c) is not balanced 2 vs. 4 Na and 4 vs. 2 O

Options b) and d) You can see the same number of atoms en each side of the equation:
2Na(2) + O(2) -----> 2Na(2)O
4Na +O(2) -----> 2Na(2)O

d is the right answer. But it is not written clearlyly (or conventionaly). That is because you can't super- or sub-script things on a computer.
It should read 4Na + O2 --> 2Na2O
