Yes, The Spouse Sponsorship is for the Permanent Residency (Family Sponsorship). But I don't remember if you should choose this option when you link your account or not. If we chose the wrong option, the system cannot find our application. Anyway, I could link my application when I followed the steps from the 2 threads that I shared to you in the previous comment. I hope it will help you to link your account successfully.
One more thing, Sponsor link account actually is not really important as it just shows you what CIC sent you.
But Applicant link account is important as you will receive all the requests and instruction letters for the next steps through that account.
Stay calm ok? Most of people here included me spent days to figure out how to link application to online account, so you can do it, just be patient.
