Parents Visitor Visa with Business background

[rawrach]

Hello everybody,

I am applying visitor visa for my parents through new IRCC portal. My father is a businessman. I have noticed that in the application, the options under employment are all job related.
After I selected "Business, finance and administration occupations" under work/activity, the drop down menu under job title doesn't have anything that relates to business, such as Owner, Proprietor etc. What is the closest option if one runs a business.

Thank you in advance!
