The results of the presidential election of 1876 angered many Democrats because they felt the South had not been fairly represented in the voting process.
Answer: Option C
Explanation:
Around 20 electoral votes from the states of South Carolina, Florida, Louisiana, and Oregon were misinterpreted. Despite of having won the popular vote, Samuel Tilden and the Democratic Party had to award the unresolved votes to the Republican Party candidate after the informal compromise of 1877. This angered the Democrats very much.
