Which of the following is an influence on conflict resolution?
a. capability
b. the nature of the conflict
c. personal attitudes
d. all of the above

I choose d. all of the above.  You have to know the nature of the conflict in order to resolve it. Apart from that, you have to make sure that you are capable of handling this situation.  Knowing a person’s attitude can help because it helps you approach the problem by reaching out to that person in a way that he or she can open up to you.  All three are necessary and can be a big influence on conflict resolution. 

all of the above because resolving conflict can tie into all of the following, you need to be capable of handling problems, and the nature of conflict as well. Personal attitudes can be affected as well because when you resolve conflict, you can better personal attitudes.
