Can one say
a. I know dancing.
My feeling is that the sentence is a bit odd.
It seems to be saying that I have a lot of information about dancing (eg. I can tell if someone is a good dancer or I know different styles of dancing etc....). It is a bit like 'I know baseball'.... I am well-informed about dancing...
I think even someone you can't dance but has a lot of knowledge about dancing could say that. That sentence does not imply that I can dance.
Am I correct?
You are correct.
