What is genocide?
a. the extermination of an entire race
c. owning an entire race
b. moving a race to another territory
d. the same as assimilation

The answer is letter a. the extermination of an entire race.  You are literally targeting an entire race or specific group of people to be wiped out.  The reasons for this can be out of prejudice or because they want something that belongs to that group or race of people.  Cases of genocide can be seen in the treatment of the Jews in World War II.  The war in Cambodia where the Khmer Rouge overthrew the government and the conflict in the former Yugoslavia.
