Option B

Explanation:

The Border Ruffians were Missouri slave-state pro-slavery demonstrators. They crossed the state border from the period 1854 -1860 to Kansas Territory as to compel slavery to be recognized there. Armed Ruffians intervened with territorial elections and hitted settlements in the Free State. The term "Bleeding Kansas" originated from this violence.

Bands of armed Ruffians occupied polling places when elections were held in Kansas Territory. They prohibited people from voting for Free-State, so they cast illegal votes. Border Ruffians voted a territorial delegate pro-slavery to Congress on 29 November 1854.
