The correct response is: By allowing enslaved people to be counted as a 3/5 of a person in Southern states, it gave Southern states more representation in Congress.
The Three-Fifths Compromise, which counted enslaved individuals as three-fifths of a person for the purposes of congressional representation and taxation, effectively increased the political power of Southern states in the House of Representatives, as it allowed them to have a greater number of representatives based on their population, even though enslaved people could not vote.
