I have this quiz:
__ he tried to cover up the truth, it came out at last.
A. No matter what
B. Whatever
C. No matter how
D. However hard
The given answer is D
but I think all the four are right.
My reason is that the following sentences both make sense to me:
- He tried everything to conceal the truth. =>
what
- He tried very hard to conceal the truth. =>
how
