C- they will look at how you have set up the letter, it is their initial impression of you. at a business standpoint you will want someone who can write a professional looking document
I believe that the best answer for this question is "are." You are referring to two parties here, both the lion tamer and the clowns. This would mean that your applicable verbs must also be plural. Since "are" is the plural version of "is," it is the most suitable word to use in this situation. Hope this helps.
