Hey there!
Your answer is B. a focus on national unity and militarism.
As national unity was becoming a big, important thing in Europe, different things were seen as a threat to national unity depending on the country.
Fascism suppresses opposition and usually has a dictator. In fascist countries, the dictator usually kept power by suppressing another group and claiming superiority over that group.
They claimed that this group would ruin the unity that the country had. The militarism would continue to support the dictator and help oppress the other group.
Hope this helps!
