#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
B because if you put too many words in the sentence it makes it confusing and doesn't make a lot of sense!
The correct option is B: 'Some people like cats better than dogs.' This option uses 'better,' the correct comparative form. The other options either misuse comparative and superlative forms or contain grammatical errors.
