There is an ongoing debate over the role of money in elections

There is an ongoing debate over the role of money in elections. The Bipartisan Campaign Reform Act (BCRA) of 2002 banned soft money and restricted advertisements in the weeks before an election. Parts of this act were challenged and struck down in the Supreme Court case Citizens United v. Federal Election Commission (2010). Wich of the following was a consequence of that ruling'.

a) The Federal Election Commission cannot place any restrictions on political advertisements because they are protected by the freedom of speech

b) Super PACs may spend unlimited funds on advertisements that are not coordinated with the campaign because they are protected by the freedom of speech

c) Advertisements produced in coordination between campaigns and super PACs cannot be restricted because they are protected by the freedom of speech

d) The Federal Election Commission can place restrictions on all advertisements because they are not protected by the freedom of speech
