The correct answers are B) populist and C) Greenback.
Debt-ridden farmers formed the populist and Greenback parties in the late1800s.
The Greenback-Labor Party had its peak moments in 1874 until 1889. The Greenback party had a platform against monopolies. The farmers wanted to still use paper money or greenbacks to help them to pay their bills. The Populist Party was founded by James B. Weaver and Leonidas L. Polk. In 1892 they formed an alliance with farmers and industrial workers. They named James B. Weaver as its candidate for the Presidency. So it is correct to say that debt-ridden farmers formed the populist and Greenback parties in the late1800s.
