All of the options describe effects that the Black Death had on medieval society. However, if you are looking for the most accurate answer, "anti-Semitic violence increased" is a direct consequence of the Black Death.

The wealthy seeking refuge in cities during the outbreak, increased trade due to the need to rebuild and renew supplies, and the establishment of new villages to replace those destroyed by the plague can all be attributed to the far-reaching impact of the Black Death on medieval society.
