First, this is one of the English test in Korea. the answer is 'c'. But some say the answer is wrong, because this sentence is a mixed conditional, so right anwer is 'a'. We are not native English speaker, so I want to know what native English speaker think of it. Which is correct between 'a' and 'c'?
And, can I use 'she would be on TV by now' or 'she might be on TV by now' or any suggestion? (sometimes modal verb is very tricky for non-native speaker)
