A & B are both correct
Not accepting other people's differences can definitely lead to disrespect. It is like you are segregating yourself away from people who are different from you like they have a contagious disease. That is not how we should treat others. We all must accept each other for our differences in race, religion, gender, sexual orientation, our view on politics, etc. We must treat each other with respect. Not accepting our differences is a horrible act that can cause contentions and can lead to many disasters that can include physical and verbal abuse.
