It is saying Tôi nghĩ cô ta yêu tôi as a second accepted answer - I have never seen cô ta before!
What is co ta
An alternative to Cô ay
Would "Tôi nghĩ cô ấy yêu mình" also be acceptable?
In this course, we've limited the personal pronouns and you can only use "tôi" for "I" and "me". Other answers won't be accepted. Please review the Tips and Notes of skill Basics 1 to recall this.

When do you add "rằng" to sentences?
Tôi nghĩ "rằng" cô ấy yêu tôi
They may have included rằng since your post, but I just used Tôi nghĩ rằng cô ấy yêu tôi and it was accepted, so những ngày hạnh phúc.
What is the difference between nghĩ and suy nghĩ?
"Nghĩ" and "suy nghĩ" are the same # think (v). But "nghỉ" is nghỉ ngơi # rest (v)
and you were wrong:))
Cô ta?? This course is very suddenly getting overloaded with stuff that hasn't been covered yet. And this chapter in particular is overloaded already with seemingly a new verb in every single step. Too much!! I'm losing all motivation to carry on.
but the option is "Co ta" not "Co ay"
