Your first consideration should be whether to respond to this kind of question at all. Answering questions about your spending habits can send a whole host of bad people your way. Its nobody's business how you spend your money.
The way it's worded is ambiguous. How you respond depends on how you feel about this kind of intrusive question.
You would be responding correctly if you chose one of the categories (perhaps one you didn't spend any on) and gave that amount- zero.
If you are for some reason eager to give a full accounting, you could add up your spending in each category (some may be zero, as you pointed out) and give the total.
The question does not ask for details.
If they want details, they should ask how much you spend on each instead of any...
If they want a total, they should ask for your total spending in all the following categories (or something similar).
