Just write in your information as an individual / I do think many folks over-think things like this
That said, I personally have felt that a C&R collector accused of 'selling' as a biz could argue with showing the application form and saying, hey??? The C&R you get sent says can not be used to for a business.
I think the first time I applied for one, I simply circled the individual and wrote my info in, but I don't remember....
