Which sentence is written correctly? a. of the three, ruth worked on her project the most slowest. b. that film started more later than the other one. c. chen answered the questions most eagerly of all. d. my cat is more bigger than yours.

C.Chen answered the questions most eagerly of all. The others are wrong because: 1) "most" is a superlative word and so is "slowest" so they shouldn't use them together. 3)"more" is a comparative word and so is "later" so they shouldn't be used together. 4) "more" and "bigger" are both comparative so they shouldn't be used together too. The point is: two comparative or superlative words shouldn't be used together.Eagerly is not a comparative or superlative word so it can be used with "most"
