It looks to be that choice "A" has been cut off. If not, then C should be your answer!
There are no "shown" because you didn't give us anything, nobody can help without resources for questions like this!
A antonym for "old fashioned" is new, because when something is old fashioned, it's usually old, and doesn't look in a good state, while something is new, it looks better than something old fashioned, or up to date
I hope this helps! :>
Popular vote is the amount of people voting, so its basically the direct vote the candidate receives. Electoral college is what we use in the U.S to elect presidents. So basically you cast your vote, and that vote goes to the electorate, the candidate that gets the most electoral votes, wins. Hope I helped!
