The best answer is:

b. famous than the cuisine of England

Here's why:

• We're comparing the fame of French cuisine to English cuisine.
• "The" is used before "cuisine" in both parts of the comparison because we're referring to specific cuisines.
• "Than" is the correct conjunction to show the difference in fame.
• "As" wouldn't be appropriate here because it suggests equal fame, which isn't the case based on the sentence.
• Options a and c are grammatically incorrect.
