The correct answer is C) It may not be given to independent groups.
What is true of soft money today is that It may not be given to independent groups, it may be used for educational purposes.
Today, soft money is not regulated. Soft money is the amount of money people donate to any political party, but this money does not have the purpose of helping directly a candidate, but for different matters. With this money, political parties can use it in their own discretion and there is no limit to it. They use this money to promote voter participation. On the opposite, when people donate to a specific candidate, then it is called Hard Money.
