So to confirm, based on answer C: You don't need all the facts in the stimulus to contribute to the sufficient condition for it to be correct, you just need the sufficient condition to be valid based on any number (some or all) of the facts present (assuming necessary is valid as well)?

Would a necessity vs sufficiency argument also work for B being correct? Basically saying economic growth is sufficient, but not necessary for benefitting the businesses, therefore they may not always benefit.
