Select the answer that BEST summarizes the article What is super Tuesday and why is it important from newela.

A
Super Tuesday will fall on March 3 this year, after the four early voting states of Iowa, New Hampshire, Nevada and South Carolina. Fourteen states will hold nominating contests on Super Tuesday. Even though Super Tuesday is one of the most important days in the presidential primary contest, it is far from the final day of voting. States around the country will continue to hold primary votes all the way until June.

B
Super Tuesday is always a major event on the presidential primary calendar, but this year's Super Tuesday contests promise to be even more important than usual. March 3 will hopefully provide answers to some major questions facing Democratic voters and candidates, including whether Bloomberg performs well, whether Biden and Warren will be able to stay in the race, and whether anyone can gain enough support to slow the momentum of the current frontrunner, Sanders.

C
Super Tuesday is the most important single day of presidential primaries. Although no candidate can win the party's nomination on Super Tuesday alone, the candidates will compete for more than one third of all available delegates, and the outcome can secure or end a presidential campaign. Super Tuesday this year will be even more important than usual because California will participate for the first time, and the Democratic nomination is still open to many candidates.

D
Super Tuesday will be the biggest day of the primary process for the Democratic presidential candidates. Every four years candidates participate in presidential primaries, which help each party decide who their nominee for president will be during the general election. Although the Republican Party is also holding primary contests this year, they are less important because President Trump does not have any major primary challengers.

C

Super Tuesday is the most important single day of presidential primaries, with more than one third of all available delegates at stake. Candidates will compete to secure or end their campaigns, and this year's Super Tuesday will be even more important than usual due to the inclusion of California for the first time and the number of Democratic candidates still in contention.
