Answer:
B. Violent acts against Jews and their property led Jews to seek a safe environment in their own land.
Explanation:
According to Encyclopedia Britannica "Anti-Semitism is hostility toward or discrimination against Jews as a religious or racial group."
The term was coined by Wilhelm Marr in 1879. It described the anti-Jewish campaigns occurring in central Europe at that time.
This anti-Semitism forced Jews back to Palestine which was their only safe haven.
