I have two ads: ad A and ad B. Ad B has CTR that is 7% worse than of ad A. Ad B is not really a bad ad, it's just a bit worse than A. Anyhow, I wanna try a new ad C and I don't wanna run B anymore since it's clear A is better than B.
In this situation, should I?
1) delete B and add new ad C
2) edit B to reflect C's text, etc
3) pause B and add C
