There's more than one way to write a correct sentence - don't interpret one correct sentence to mean it can't be written another way. I could say:
She doesn't like playing sports but does like watching them on TV.
or
She doesn't like playing sports, but she does like watching them on TV.
Both versions are grammatically correct. It is not required to repeat the "she" in this construction, but you can repeat it if you want. So the correct answer could be written either way - you have to go check the choices and see what you are given. (And they wouldn't give you two totally grammatically correct options, one with "she" and one without "she" - then you'd have two right answers!)
