citizens vote for delegates in primaries and caucuses and delegates then select the candidate at a national nominating convention
Delegates from all the states meet and elect a candidate for president and then for vice president, Nowadays so many of the delegates are committed to a particular candidate by primary elections that one candidate can have the nomination "sewed up" before the convention occurs and lately it has been the custom to let the presidential nominee pick his running mate.

To decide a party's candidate for President, states may use a variety of means -- chiefly primaries and caucuses -- to choose delegates to a national convention. These delegates, often pledged to a particular candidate, will choose the party's national candidate.

C and B are both correct, I think. National primaries award votes to candidates at the conventions, but not all states have them and there are other delegates that are not bound by primaries. In recent years, one candidate has won so many votes in primaries that the nomination is either locked up or almost locked up, but it is possible that no candidate would have a clear edge when the convention begins. Primaries only bind delegates for the first ballot.
