Which of these sentences is written correctly? a. the closet keeps getting more fuller. b. that dog gets fatter every day. c. the most quickest way to feel better is drink water. d. the family next door is the most loudest in the neighborhood.

B. That dog gets fatter every day 

B. That dog gets fatter every day. Check it out: 

A is incorrect because of the tense of fuller combined with the word "more." The correct tense would be, "more full." C is incorrect for the same reason. The correct tense would remove the "most" and leave the word "quickest." D also applies for the same reason. We once again would either delete the "most" in that sentence, or we would change the tense of the verb to "loud."
