A) is much more better, or at least as better, as any
B) is much better, or at least as better, as any
C) is much better, or at least as better, than any
D) is much better than any
E) is more better than any
OA to follow soon, source Aristotle SC
Please explain

We can eliminate A and E because they use "more better".
"is much better, (...), as any" is wrong, the correct idiom is better than: out B.
We have left C and D. My pick is D. In C ",or at least as better," should have a "as" to complete the idiom "as better as".
Waiting for OA...
Good explanation here. I would only add that for C, the construction "as better as" would have to be "as good as". Really, if you wanted to fix C it would need to go as follows: is much better than, or at least as good as, any
