Have you ever been in a situation ______ you know the other person is right

[chance22]

"Have you ever been in a situation ______ you know the other person is right yet you cannot agree with him?"
In the above sentence, should I use "that" or "where" in the blank? I'm not sure about that. Would you help confirm it?

 

[5jj]

I'd use where or when.

 

[Rover_KE]

Definitely not ‘that’.

 

[jutfrank]

where
that

 

[teechar]

where or in which, but where is better .
that doesn't work in that sentence.
