Which one is correct? Are there any mistakes?

The first is grammatically correct. There is no need to separate it into three sentences. Doing so does exactly what I generally discourage learners from doing - starting sentences with "and" and "so" (and "but").

What is the purpose of your examples? What does "the owner" own?
