Which on is OK? I'm sorry I can't be more help. I'm sorry I can't be of more help. I'm sorry I can't be more helpful.

All three are good. I wouldn’t split hairs on the differences. To do so is just a waste of time.

The first one is not correct!

The second one sounds good and it is acceptable to be used in a sentence, but the third one sounds more natural and it is more commonly used!

Best option: "I'm sorry I can't be more helpful"

Hope that helps!

Even though the third one sounds more natural, the second one is also acceptable.

I believe third one is better than others.
