Answer:
Discrimination
Step-by-step explanation:
1) diversity --- not diversity
2) discrimination --- possibly discrimination. Discriminating against other groups.
3) inclusiveness --- means to cover many areas, not the case here. He is covering only his area.
4) persecution --- ill treatment based by race, or political beliefs.
I am not considering "men" on his team, because it doesn't apply discrimination. He simply is just biased to his people. Which is a group. However he is not just persecuting someone. Best answer is discrimination.
