The first and third answers are definitely correct (the first being a subset of the third), so I went for 'all of the above'. A good question, spoiled slightly by the choice of answers.
Ditto here.
#2 is not 100% clear and leaves a little too much room for interpretation. But since 1 and 3 are definitely right, the only possible answer had to be all of the above.
