D)none

• 3 men = 8 boys
  1 man = (8/3)boys
  2 men + 6 boys = (16/3)boys + 6 boys = (34/3)boys
  
  8 boys can do a piece of work in 17 days
  (34/3)boys can do the same work in (17*8*3)/34 days = 12 days

• Form the given problem 3m can complete the work in 17 days so 1 day work is=1/17
  m=1/51
  8 boys can complete in 17 days 1 day work is=1/17 then b=1/136
  then 2m+6b can do 2(1/51)+6(1/136)=289/3468
  then it will take 12 days to complete the work
  option C is correct
