Question

Which sentence is correct?

Answer 1

#2 is correct.

Problems with the others:
#1 - best is a superlative (used to compare more than three or more things)
#3 - best is the greatest something can be so you cannot have more of it
#4 - you either use "more" OR "better" because "more better" would be just be the best

Answer 2

B because if you put too many words in the sentence it makes it confusing and doesn't make a lot of sense!
