The one that's closest to the verb
is:
Ex: A plumber is a person whose job (that) it is to repair the pipes. <subject + verb>
Omit
it and
whose job becomes the subject:
Ex: A plumber is a person whose job is to repair the pipes. <subject + verb>
--------------
I don't find the phrase
whichever one awkward here:
Ex: Take whichever one you want. 
But it is awkward here:
Ex: Whichever one broke the window will have to pay. 
Meaning, a thing broke the window and it has to pay.
Ex: Whichever one of you broke the window will have to pay.
Meaning, a person broke the window and s/he has to pay.
Does that help?
