Which sentence is written correctly? a. ken jumped more farther than any other long jumper. b. friday was more rainy than the day before. c. siobhan's house is more closer to the stable than yours is. d. rose's story was the most shortest of any student's story.

To me, none of these sentence sound correct. However, I believe that the only sentence which could be considered correct is B) Friday was more rainy than the day before. Although I would put rainier. 
A should be - farther, without more.
C should be - closer, without more.
D should be - the shortest, without most.
