Which is an example of antiracist behavior?

I believe the answer is: Rachel says it's wrong to say negative things about Latinos based on a stereotype

Antiracist behavior refers to a set of behavior that carried out in order to prevent a certain social group from being prejudiced / treated unfairly by others.

This behavior is shaped through the awareness that every single indirect prejudice that we do is contributing to the perpetuation of racism in a society as a whole.
