Hello!
I think Mark was using summarizing, because of the way Mark phrased his sentence. "The main point" does invoke a summary of a sort. Now, C is possible, as well, but not likely. I'd suggest sticking to A.
Have a wonderful day! :)

If its not b i think it would be c

I think it’s figurative if it’s wrong sorry!
