The examination was not very difficult, but it was _____ long.
A. too much
B. so much
C. much too (key)
D. very much
I am wondering whether D is also all right besides C, please?
Things can be too long. They can be very long. But they can not be much long.
In "C" it is saying it was "too long" and "much" modifies "too."
In "D" it is saying it was "much long" and "very" modifies "much."
But we do not say "much long."
Thanks for clearing up.
