Final answer:
PACs are not solely funded by the government, but rather by donations from individuals, corporations, and unions.
Step-by-step explanation:
The correct answer is d) PACs are solely funded by the government. PACs, or Political Action Committees, are formed by organizations, including interest groups, to raise funds and contribute to candidates in federal elections. They are not funded solely by the government, but rather by donations from individuals, corporations, and unions. PACs can contribute directly to political campaigns, are restricted in the amount they can donate, and must disclose their donors.
